S4·E21 The Ivy Maze

Fritz Simmons is a college professor doing research on sleep depervation. One of his patients is the one-armed man Fred Johnson, whom works as a groundskeeper at Wellington College. When Johnson begins talking in his sleep about having killed a woman, Fritz contacts Kimble. When Kimble arrives, he verifies that it is indeed Johnson, and he and Fritz realize that by recording Johnson's confession will prove Kimble's innocence. Meanwhile, Gerard has found out about the experiments from Fritz's wife Caroline, and believes that Kimble may be on the premises. Gerard's arrival at the facility leads to an incredible confrontation between himself, Kimble and the one-armed man.
