Cole convinces himself that he is insane, but Railly confronts him with evidence of his time travel. They decide to spend their remaining time together in the Florida Keys before the onset of the plague. On their way to the airport, they learn that the Army of the Twelve Monkeys was not the source of the epidemic; the group's major act of protest is releasing animals from a zoo and placing Goines' Nobel Prize winning virologist father (Plummer) in an animal cage.
