Undercover Blues is a 1993 movie about a family of secret agents, starring Kathleen Turner and Dennis Quaid. The film was directed by Herbert Ross.

We start at a lively and festive party in New Orleans, where we meet Jane and Jeff Blue (Kathleen Turner and Dennis Quaid) with their baby daughter, whose name the parents still can't agree on. There they meet another couple, the Newmans (Park Overall and Tom Arnold) and get acquainted. Jeff first tells them he is a neurosurgeon but then Jane truthfully tells the Newmans Jane and Jeff are spies. Of course, the Newmans believe they are joking.

On the way back to the hotel from the party, Jane asks Jeff to get the baby some formula. Jeff agrees, taking baby Jane Louise... or Louise Jane... with him in a stroller. He deliberately takes a turn onto a seedy alleyway, where he is confronted by Muerte (for Death, Stanley Tucci) and Ozzie (Dave Chappelle), who attempt to mug him. After giving him his wallet and Swatch, he promptly makes mincemeat out of them, carrying the baby in one arm, and jousting with the stroller in the other. Ozzie smartly plays dead, while the stubborn Muerte (by now called Morty by Jeff) faces another blow by the stroller, losing a tooth in the process. Later on, recouperating at a bar, Muerte gets his chops busted by some cronies, who get a taste of some broken glass and Muerte's fist, in his only successful act of violence in the film.

Calmly walking on as if nothing happened, Jeff returns to the hotel suite with the mangled stroller. Ignoring Jane's question about how it got that way, Jeff notices two policemen talking to the hotel manager, who identifies Blue and sends them on up. Giving Jane the heads-up, Jeff lets Lieutenant Theodore Sawyer (Obba Babatunde) and Sergeant Halsey (Larry Miller) in. The detectives are investigating a series of muggings, and heard that a man with a baby stroller successfully escaped the crooks. Jeff asserts he has no knowledge of the incident, and that he is just a simple Electrolux salesman. Jane provides face support for her husband, backing him up, but then quickly chews him out for endangering his and the baby's lives once the cops leave. They soon make up however, and Jeff promises to be smarter about the fun he has.

The Blues carry on with their vacation, when Jeff promises Jane they are now in "chapter two" of their life, "where Jeff and Jane lead a sane, normal life." That lasts about one day, when Jeff notices an intruder. Jane does some quick reconnaissance, noting it is one man on the couch reading. Jeff quickly takes him down with a flying tackle, then gets off of him when he realizes its Frank, their supervisor (Richard Jenkins). He has a difficult job ahead of him: to coax Jeff and Jane out of maternity leave in order to handle an extremely dangerous situation. It seems that Czechoslovakian arms trader Paulina Novacek (Fiona Shaw) is hiding out in the bayous of Louisiana, setting up a crime ring to steal a batch of C-22, a highly volatile, extremely unstable explosive to supply terrorist organizations. She bribed a full colonel into stealing it for her, but when she learned he used one of the five canisters to escape authorities, she dispensed with him by pushing him down a grain silo. After promising a subtantial bonus to the Blues, they accept Frank's request for help in capturing Novacek and begin research right away.

Novacek's henchmen call on Gilbert Foster, a meek and disgraced scientist, to help fund the C-22 operation. They set up plans to "deliver the merchandise in the usual place." Foster's file is already in the Blues' hands when they meet up with the bumbling detectives, who have been doing some research of their own. They've learned the Blues are spies, though they can't figure out who they currently work for. They sit down at Cafe du Monde for coffee and beignets to try to get some answers from Jeff. However, he's more interested in the bank robbery in progress across the street, and single-handedly foils the hold-up and captures the bandits.

In thanks for his help, the cops promptly arrest Blue, where a call from the Louisiana governor's office eventually leads to his freedom. Back at the hotel, Jeff receives a phone call from Muerte, attempting to be threatening. Jeff is not to be ruffled, and hangs up on him. He says that 'Morty' will be very useful in the investigation.

Jeff spends the next day waiting for Foster at Dynagon Industries. Pretending to be a reporter working on a story about theft of defense secrets, Blue successfully scares Foster enough to call his middleman, Mr. Furderber, at Rampart Savings & Loan. Foster deposits a security camera photo with a warning note into the bank's ATM. Ferderber, the bank president, collects it out of the machine and faxes it to Novacek's base in the delta. Knowing now that the Blues are onto them, she orders the operation to be accelerated.

The Blues spend a restful day shopping for a new stroller and a post-feminist Missy Prissy doll ("She goes to work with little sneakers on but resents it," claims Jane), knocking out more of Morty's teeth as he continues to attack them, then head to an open-air restaurant for some oysters. Jeff soon asks if the oysters come with guns, as the table seated next to them is filled with Novacek henchmen. Morty then arrives with oysters and a growl in tow, which soon turns to a girlish scream when he sees all the guns pointed. Then all hell breaks loose, as the Blues throw Morty's serving tray and a table at the henchmen, allowing them enough time to drop-kick Morty to the ground and make a break for it.

Sawyer and Halsey catch up with them just as they leave. Jeff amicably answers Sawyer's questions with comments about The Honeymooners and joining in a street parade. Evidently only he knew he could play the trumpet.

Jeff makes a phone call to Foster in the guise of a Novecek henchman. He arranges a meeting with Foster at "the cemetery where we always meet" for the next day, intending to spook Foster enough to get information from him. Then Jeff 'kills' the lights and the Blues spend a romantic night together.

The detectives meet up with the Blues the next day on a trolley down New Orleans' beautiful main street down to a cemetery. Jeff seems to be enjoying the funeral music, but Sawyer is more interested in digging for more answers from the Blues. The only thing he manages to uncover is Foster's body, which was unceremoniously stuffed in an opened mausoleum.

The Newmans arrive that night to pick up their child, which the Blues spent the rest of the day babysitting. Once they leave, Jeff tugs Jane close to him, with plans for a really "fun evening."

The fun involves picking the lock of Foster's house and searching it. What they find there is Sergeant Halsey's rather large feet and another set of questions from Lt. Sawyer. Knowing now they can't cover up any more, they begin telling the story of Novacek's operation and their objective--explaining that the government was not going to extradite Novacek, and that she has to go back to Czechoslovakia voluntarily. Jane happens across a table with its base filled with money. While Halsey's not upset over seeing lots of money, Jeff is--they were hoping to find the name of the guy Foster was funneling information through. As they leave Foster's place, they notice another Rampart branch across the street. Their files indicate Foster used a branch across town. But why, hmm?

Acting on a hunch, Jeff plans to smoke out Ferderber by sending in the detectives into his branch, obnoxiously shouting questions at him. Ferderber leads them into his office then promptly heads out of the building where Jeff immediately forces him into Sawyer's car.

We next see Ferderber strapped to a chair in the Blue's hotel room, now barren except for Jeff and a bare light bulb. Jeff introduces him to Dr. Natasha Lottelanya (Jane in a maintenance coat), and begins to talk about her work in the field of extreme pain. They demonstrate her newest invention, "Jane's Probe," really a pair of sewing needles attached to an electrical box. Their plan is almost foiled when the noise of the live current wakes up the baby, in the next room crying. Jane goes to attend to her while Jeff makes a brilliant cover--"That's Professor Lancaster. He was really a tough one when he came here. Now listen to him." A profusely sweating Ferderber spills the beans, providing them with all the info they need. At this point, Morty shows up again at the back door as the detectives begin knocking on another. Frightened, Ferderber bolts, knocking himself and Morty clear off the balcony. Sawyer then busts in, demanding to know where his car went. Jeff doesn't reply, but instead tells the detectives they're off to the zoo.

Jeff, Jane, and the baby now walk casually through the zoo, stopping to watch a group of tigers sauntering in their pen. They soon spot both the detectives and--yet again, Morty, tracking their every move. In order to take care of Morty, Jeff sets up a diversion for Jane. Much to her dismay, the diversion involves pretending she's having an epileptic seizure to keep the detectives with her.

The plan works beautifully, and Jane takes the opportunity to bite Sawyer's finger hard as he tries to prevent her from swallowing her tongue. Meanwhile, Jeff lures Muerte to the gator pool, and when he rushes towards Blue, Jeff easily flips him down into the pit. Now frightened beyond belief, Morty begs Jeff for help. Jeff agrees--but not after demanding Morty for his wallet to repay the cost of the stroller he ruined. Morty tosses the wallet. Jeff takes his cash, and places a small blue geosynchronous positioning device deep in the wallet before tossing it back. As the gators become hungrier, Jeff further humiliates Morty by making him take off his jacket and pants to make a rope. They just don't make a long enough rope to be of use, so Jeff leaves to "get help."

The only thing Jeff does get is a wide grin and a friendly hello from a Catholic girl's school on a field trip. ("Hello, Sister. don't miss the gators.") Returning to Jane, he pretends to give her some medication, which immediately stops Jane's convulsions. Exhausted, they get back on the trolley to head back to the hotel. On the way there, Jeff tells Jane he has more "fun" planned for her.

That night, Morty goes back to his favorite watering hole, still soaked with swampwater and pulling moss out of his wallet. A bag lady sitting next to him identifies him as "the feller who got stomped by the man with the baby." She claims to know how to get back at him, knowing someone who'll pay big money to Muerte if he accepts. Muerte's interest is piqued, and she gives him all the necessary info. The bag lady turns out to be Jane doused in heavy makeup and a wig, and she returns to the hotel in the early morning hours to a waiting Jeff.

Muerte calls the number the bag lady gave him, which turns out to be Novacek's headquarters. He says he has information on Blue and would be willing to share it at the right price. Novacek sends a team of her man out to collect Muerte and bring him to her delta hideout. However, Novacek distrusts the Spaniard and strings him up over a silo, convinced he is working for the Blues.

Thanks to the GPS device in his wallet, the blues now know exactly where Novacek is. Jeff immediately rolls into action, telling Jane he'll be careful and that he loves her very much. While Jeff gets some last minute sailing tips from a pier captain, Detective Sawyer sneaks onto the boat Blue will use and hides out. Jeff climbs aboard, and sails off in the direction of Muerte's signal.

Jane remains at the hotel still worried about Jeff when the baby begins to take her first steps. Overflowing with joy and praise, Jane snaps a few Polaroids of her brilliant baby. But there's no time left for play. The next time we see Jane, she's pushing a new stroller down the alleyway and is met up by two of Novacek's men. She gives a hard fight, but has to surrender when threatened by a high-powered Taser.

Jeff arrives at the dock of Novacek's hideout and is almost immediately confronted by Sawyer. Annoyed, Jeff agrees to let Sawyer follow him, but warns him things could get very sticky. No sooner does he utter the words then Novacek appears behind the next corner, backed by more henchmen. Jeff and Paulina trade very civil pleasantries before Novacek has him cuffed and gets down to her warehouse headquarters to talk shop.

The first thing Jeff sees is Jane and the baby, flanked by gunmen. Paulina agrees with Jeff that capturing Jane and the child was in bad taste, but that they could be used simply as an example to Jeff of what she can do, should Jeff refuse to give her government secrets. Paulina shows off Muerte, bound on the floor, bragging that she has captured all of Blue's confederates. Jeff surprises her however when he tells her that Muerte, "The Big M," is his boss. An enraged Muerte tries to attack him but doesn't get far. Paulina then demands Jane to hand over the baby. Jeff simply says, "Jane. You know what to do." Jane nods and sorrowfully picks up... the Missy Prissy doll. She tosses it in the air and it explodes, causing enough of a commotion for Jane, Jeff, and Sawyer to escape.

Her plan crumbling, Paulina makes a desperate flee to a salt mine underneath the compound, where she has hidden the C-22 canisters. Jeff, Jane and Sawyer follow close behind, with Jane skillfully blowing away henchmen left and right. A helicopter flies by, ready to pick up Paulina and the explosives. However, the case is too heavy for her, and she falls into a pit of mud as she tries to climb the chopper's rope ladder. Jane swings by holding onto a crane hook (operated by Jeff) and plops into the mud beside her. They wrestle and struggle for control of the case, but Paulina ends up on top, ready to kill Jane with a foot to the neck. She is distracted by Jeff, now holding a flamethrower Sawyer found. He keeps turning the flame on towards the case of C-22. She is distracted long enough for Jane to knock her down and hold her there.

The men in the helicopter then draw their weapons and order everyone into the mud and stay down until Paulina gets in and leaves the scene. Everyone does as told, and Paulina gleefully enters the helicopter. As she tries to clean herself up, the man in the co-pilot's seat of the helicopter, Frank, puts a pair of cuffs on her, welcoming her aboard 'Air Czechoslovakia.' The helicopter was part of the setup to make Novacek believe she was escaping. As she voluntarily got into the chopper, she can now legally be taken back for trial for crimes against humanity in her home country.

Sawyer drops the Blues back off at the Hotel after the fracas, and the Blues give them his word they're leaving New Orleans that day. Sawyer jokingly asks if they have plans of invading Cuba while they're at it. At the hotel, they meet up with the Newmans one final time. They were babysitting the real Jane Louise (the name now agreed upon by the parents).

As the movie ends, the Blues get on board a luxury yacht prepared to enjoy the rest of their vacation time. They have one more encounter with the stubborn Morty, knocking him into the ocean with their sail. They toss him a life ring and leave him to float there as they sail towards their next destination. And where is that? Cuba.
