And...?
Vincent works as an in-valid, cleaning office spaces including that of Gattaca Aerospace Corporation, a space-flight conglomerate. He gets a chance to pose as a valid by using hair, skin, blood and urine samples from a donor, Jerome Eugene Morrow, who is a former swimming star paralyzed due to a car accident.[5] With Jerome’s genetic makeup, Vincent gains employment at Gattaca, and is assigned to be navigator for an upcoming trip to Saturn’s moon Titan. To keep his identity hidden, Vincent must meticulously groom and scrub down daily to remove his own genetic material, and pass daily DNA scanning and urine tests using Jerome’s samples.
