Vicky (Ashley Benson) is a young woman looking for an escape after going through a harrowing break-up. After retreating to a friend's remote cabin in the woods to clear her head, she continues modeling sexy lingerie for her devoted followers on 18 & Over, an adults-only, live-streaming website. But when the power keeps going out, Vicky discovers something terrifying awaiting her in the dark -- a masked killer wielding a crowbar who's hellbent on bringing her night to a grisly end.
