Sleeping at night has become a luxury for Peter (Michael Pna). Again, and again he has this one dream in which aliens attack and kill his family.
While he is convinced that these are visions of the future, nobody else takes him seriously, not even his wife Alice (Lizzy Caplan). He should go to the doctor, it is said again and again, especially when the nightmares start to even take him physically. But then the unbelievable happens and there is actually an alien invasion. As Peter, Alice and their two daughters (Amelia Crouch, Erica Tremblay) desperately try to escape, it dawns on them that there is much more to the dreams than they anticipated.
