Fringe - Season 5 (2012)

An act of kindness by Peter draws attention to Etta. The Observers deal with an infiltrator, and we learn of a resistance leader known as the Dove and, coincidentally, that Phillip Broyles is working with the Observers.

Peter, in the grip of mourning Henrietta's death, resorts to extreme measures in order to gain powers that will allow him to surpass those that the Observers possess and hopefully, and eventually, find a means to defeat them.

Walter retrieves another video tape from the amber and it leads the team into a pocket universe.

The team retrieves another cassette tape from the amber. With Nina Sharp's help, the team recovers 2 cylinders. While Peter works independently to score a minor victory against the Observers, Olivia ascertains Peter's secret.

Following the bread crumbs, Olivia collects a truck with cargo from a scrap yard but runs into bounty hunters. Peter, with newly gained powers, has to make a decision.

Walter Bishop opens Pandora's Box. He finds a young Observer once he has hidden in the Pocket Universe.

Young observer remains muted. The team seeks Nina Sharp's help to understand him, but the mission is compromised.

Young Observer's origin is revealed. And his existence and an additional time travel are necessary to change the history of Observers' invasion.

As the Observers evaluate Michael and begin to learn of his abilities and potential, Olivia embarks on a dangerous quest to rescue him.

As the Observers close in, Walter and September desperately work to complete the plan, but one obstacle after another hinders their progress.
