Fringe - Season 5

Picking up from the ominous events of last season's Letters of Transit, the year is 2036 and the Observers rule is absolute. The Fringe team - preserved in amber for 20 years - is now a rebel resistance team fighting for freedom. Peter, reunited with his now adult daughter, Etta, sets out to find out what happened to his wife and Etta's mom - Olivia - as they begin their mission to save the world from the Observers.

Determined to retrieve the plan to defeat the Observers from his memory, Walter Bishop tries again with the Thought Unifier to little avail. Olivia suggests the team revisit the old Harvard lab, now under Observer control, to try and find any potential information Walter may have documented as the team fights on in their mission to save the world.

As the rogue Fringe team continues to fight off the oppressive Observers' invasion, unforeseen events lead them to a forest in rural Pennsylvania, where they encounter a strange subculture of people devoted to recording human history.

As an act of kindness by Peter draws unwanted attention to Etta, Walter discovers the whereabouts of the second component to the Observers' downfall, forcing the team into a hostile and heavily guarded location. Elsewhere, the Observers must deal with a potential infiltrator, and Phillip Broyles resurfaces.

As the Fringe team reacts to a devastating loss, a key member resorts to extreme and brutal measures to exact revenge upon the Observers, and to find a way to defeat them by any means necessary.

In their continued mission to save the world, the rogue Fringe team reaches out to Nina Sharp to help complete the next step of Walter's plan. Meanwhile, Peter begins to understand the precognitive abilities the Observers get from their technological implants, and recruits Anil to test out his newfound skills.

Olivia travels to the town of Fitchburg, looking to recover a key piece of equipment for Walter, where she encounters an intuitive and oracle-like woman named Simone. Meanwhile, Peter finds himself in a perilous situation as he observes Windmark in his personal quest to avenge Etta's death.

In attempt to recall a plan to defeat the Observers, Walter takes an LSD trip down memory lane. Meanwhile, Peter and Olivia trace a mysterious signal to the woods, where they come upon a grisly scene.

As Windmark continues his investigation into the location of the rogue Fringe team; the team find themselves rapidly running out of time to save the world. As Peter, Olivia, Astrid, and Walter scramble to tap into a key piece of the puzzle to defeat the Observers, they enlist the aid of Nina Sharp who conjures up a risky plan.

With Michael having revealed the origins of the mysterious figure, Donald, Walter enters the deprivation tank in an attempt to uncover critical information hidden in his subconscious. Meanwhile, Captain Windmark travels to his future of 2609 where he meets with the Observer Commander to discuss September's past transgressions in helping the Fringe team.

In a final bid to save their world from the Observers, the Fringe team engages a desperate plan as Olivia embarks on a dangerous and otherworldly journey into the unknown.
