Society has categorized Vincent Freeman (Ethan Hawke) as a genetically inferior "in-valid," and he has become one of the underclass of humans that are only useful for menial jobs. He decides to fight his fate by purchasing the genes of Jerome Morrow (Jude Law), a perfect genetic specimen. He assumes Jerome's identity and joins the Gattaca space program, where he falls in love with Irene (Uma Thurman). Just when Vincent is finally scheduled for a space mission, a Gattaca officer (Gore Vidal) is killed and the police begin an investigation, jeopardizing his secret.
