The year is 2036. The Observers have become ruthless rulers, limiting free will and speech, and are slowly poisoning Earth's atmosphere so that only their own kind can survive. All is not lost, however. A series of videotapes, preserved in amber, hold detailed plans for overthrowing the Observers and restoring the planet and its people. The Fringe team will undertake the most important mission of all time: retrieve the tapes, follow their clues, decipher the code, and prepare for the battle to save humanity. Join Fringe scientist Walter Bishop, FBI agent Olivia Dunham, Peter Bishop, and Olivia and Peter's now-grown daughter, Henrietta, for 13 episodes filled with struggles, surprises and sacrifices in this explosive and emotional final season.
