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. Gattaca becomes embroiled in controversy when one of its administrators is murdered a week before the flight. The police find a fallen eyelash of Vincent's at the scene.
