What was supposed to be a night of comfort... became a fight for survival.

After a painful breakup, Olivia's best friends drag her to a secluded cabin for a girls' sleepover — a chance to heal, laugh, and forget. But the night takes a chilling turn when strange noises echo through the halls and one of them vanishes without a sound.

As the hours tick by, it becomes clear this is no random attack. Someone knows their secrets. Someone has been watching them. And someone isn't leaving the cabin alive.
