Immersive. Compelling. Hypnotic. Brilliantly imaginative. Endlessly thrilling. Pick your term. The mystery of the universes deepens in the critically acclaimed 22-episode third season of television's most exciting sci-fi. The Fringe team escapes from the parallel universe - except for Olivia, trapped in the other world and replaced in ours by her double, who turns Peter and Olivia's tentative relationship into a love affair. Then Olivia returns, bonds of trust fray, ever more bizarre and terrifying phenomena occur and secrets that stretch back to 1985 threaten to destroy our universe. Or theirs.
