Babysitter Ashley (Olivie DeJonge) is asked by Mr. and Mrs. Lerner (Patrick Warburton
, Virginia Madsen
) to take care of their 12-year-old son Luke (Levi Miller
), who is attracted to the older girl. Everything seems fine at first. They order pizza and begin watching a movie. Eventually, Luke's friend Garrett (Ed Oxenbould
) comes over.
However, Luke is unhappy that Ashley is spending so much time on her phone with her boyfriend Ricky (Aleks Mikic), who's unhappy that she's moving away. Later, someone throws a brick through the window with the ominous message: "U leave, u die" on it. But all may not be as it appears, and Ashley is in for some very strange surprises.
