There's more than one Observer! When one of the series' mysterious Observers kidnaps a woman, the Fringe team is called in to investigate why. But while the course of their investigation not only reveals the private lives of the Observers, it also threatens to unearth Walter's clandestine involvement with them years before – a secret he's desperate to keep from his son, Peter. As destiny is irrevocably rewritten and time is running out, the renegade Observer asks for help from the unlikeliest of sources…Walter Bishop.

While explaining Peter's otherworldly origins to Olivia, Walter flashes back to 1985 and the mystery springs forward by revealing the past. Also, Peter's mother (guest star ORLA BRADY) is introduced - and details of the neighboring world reaffirm that there is definitely more than one of everything.

As the thrilling third season propels itself to its climactic close, questions will be answered as Peter confronts his destiny and a beloved team member meets an untimely demise.

Peter and the Fringe team take extraordinary measures in an attempt to stop life-threatening events from unfolding.

An Observer makes contact with the Fringe Team to help rectify a mistake. Meanwhile, Walter befriends Roscoe Joyce, keyboardist for Walter's favorite 1970s band, "Violet Sedan Chair." Walter will learn the real reason the band broke up, and realize that the lives of these two men, who have never met before, overlap in strange and unexpected ways.
