FRINGE returns with an all-new episode, directed by Brad Anderson ("The Machinist"), as the team tackles a case involving a strange, almost-otherworldly parasite that has attached itself to the internal organs of a dying FBI agent (guest star Chance Kelly). Racing against time, Agent Dunham (Anna Torv) flies to Germany to meet with an imprisoned man (guest star Jared Harris) who reveals disconcerting details of a much larger threat. Meanwhile, Peter (Joshua Jackson) and Walter (John Noble) attempt to help Olivia by tapping into a dead man's brainwaves.
