The premise of FlashForward is not a secret:

On the show's premiere, everyone around the world blacks out, sees a version of his/her future and wakes up two minutes later, taken aback by whatever is going on.

But what, exactly, do the main characters see? In the promo below, we get a brief idea. One is in bed with a man that's not her husband; another is getting a sonogram, even though she doesn't even have a boyfriend in the present day.

Watch the trailer and get psyched for the FlashForward series debut on September 24.
