Years later, Vincent works as an in-valid, cleaning office spaces including that of Gattaca Aerospace Corporation, a spaceflight conglomerate. He gets a chance to pose as a valid by using hair, skin, blood and urine samples from a donor, Jerome Eugene Morrow, a former swimming star who was paralyzed after being hit by a car. 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, pass daily DNA scanning and urine tests using Jerome's samples, and hide his heart defect.
