For its fifth final season, Fringe is heading back to a frightening future run by scary bald men — and we have the video to prove it!

When the Fox thriller returns on Sept. 28, the action picks up the day after Season 4’s 2036-set “Letters in Transit” episode left off — with an Olivia-less Fringe crew joining the war against the Observers.

The following exclusive teaser shows the invaders marching toward the screen as a series of voiceovers recount the team’s gradual understanding of the chrome domed enigmas.
