In IMPUSE, Henry (Maddie Hasson) and her mom Cleo (Missi Pyle) have led a pretty reckless life so far, between Henry's acting out (AKA criminal misdemeanors) and Cleo's string of unreliable boyfriends in different towns. But now they've landed in a good place, living with Cleo's newest boyfriend (Matt Gordon) and his resentful teen daughter Jenna (Sarah Desjardins). Their new town is small and not that friendly; nonetheless popular football star Clay (Tanner Stine) seems interested in Henry. But when Clay's interest turns malicious -- and when Henry discovers at a terrifying moment that she has equally terrifying powers -- a series of events is launched that even Henry's newfound powers can't control.
