Erin Brockovich is an unemployed single mother of three who, after losing a personal injury lawsuit against a doctor in a car accident she was in, asks her lawyer, Ed Masry, if he can find her a job in compensation for the loss. Ed gives her work as a file clerk in his office, and she runs across some files on a pro bono case involving real-estate and medical records against Pacific Gas and Electric Company. Erin begins digging into the particulars of the case, convinced that the facts simply do not add up, and persuades Ed to allow her further research. After investigation, she discovers a systematic cover-up of the industrial poisoning (Hexavalent chromium) of the town of Hinkley's water supply that threatens the health of an entire community. She finds that PG&E is responsible for the extensive illnesses residents of Hinkley have been diagnosed with and fights to bring the company to justice.
