He attempts to recapture his former glory but is soon confronted by the FBI and asked to go undercover to smoke out a notorious criminal and ping-pong lord called Feng (Christopher Walken).

Randy Daytona is a huge Def Leppard fan. Half of the movie, he doesn't take off his Def Leppard shirt. His racket has the words on it "Def Leppard Rules". Mid movie, right before his "canceled" match with the German, Daytona pulls out a boom box and starts to dance to "Rock of Ages". He also at one point loses the ability to play ping pong with his right hand and uses his left with his right in a sling. This is an obvious reference to Def Leppard drummer Rick Allen, who lost his left arm in a car crash and continued to play with only his right. Perhaps coincendentally, Def Leppard is signed to the Universal Music Group, once under common ownership with Universal Studios (the parent of distributor Rogue Pictures).

The plot is very similar to Enter the Dragon. It also has many references to Star Wars and Mortal Kombat.
