It's a future world where genetic tinkering allows parents to tweak their children's DNA before birth and a caste system of "perfect" humans exists. Vincent (Hawke) dreams of employment with the aerospace corporation Gattaca, so he assumes the identity of the genetically superior Jerome (Law). Soon Vincent is falling for icy co-worker Thurman and getting involved in a murder investigation, which could uncover his true identity. Thinking man's sci-fi (read: no spaceships or explosions) along the lines of George Lucas' "THX-1138."
