Fringe comes back in just over a month, and we're going to be seeing a very different chapter in the saga of Walter Bishop and his crew. Check out a brand new promo above, which features our first glimpse of the action in Fringe season five!

Spoilers ahead...

So it looks like we're going to get to see what it was like when the Observers invaded from the future. And poor little Etta gets caught in the middle, between her parents and an wall of impassive men in cool hats. This looks like part of a pretty thrilling sequence. Fringe comes back on Sept. 28.
