Still reeling from her parents' divorce, April (Brittany Allen, Defiance, Dead Before Dawn) is dragged back to the vacation cabin she spent fond summers at as a child accompanied by a group of friends. Her trip down memory lane takes a dramatic and terrifying turn when a fireball descends from the sky and explodes in the nearby woods. Lead by her boyfriend (Freddie Stroma, Harry Potter and the Half-Blood Prince, Pitch Perfect), the group venture out toward the crash site and discover the remnants of a ship from another planet along with footprints that suggest its alien occupants are still alive. The college friends soon find themselves caught in the middle of something bigger and more terrifying than they ever thought possible.
