Leanne vanishes into thin air. Her children, abandoned in her car, also end up missing. As police search for clues over the next three months, Leanne's husband and family soon learn that nobody is what they seem. Everyone is a suspect. In the end, five days prove critical in solving the case.
The fifth and final season delivers a climactic conclusion.

What awaits in the future, however, is the Fringe Team's final stand, which will bring together all they have witnessed in preparation for the final battle to protect our world.
