Three weeks after her boyfriend dies in a fatal car crash, Sylvia is doing everything she can to claw her way back to a normal life. But the comforting support from loved ones is quickly drowned out by relentless, boundary-crossing texts from her late boyfriend’s best friend. She is already too terrified to tell him to stop when a silent phone call from an unknown number leaves her freezing on a dark, rainy street.

The uneasy stalking turns to absolute panic when her best friend suddenly vanishes from the schoolyard, leaving behind a trail of unanswered calls. Tracking her friend’s phone leads Sylvia to a desolate alleyway behind the school, only to find her belongings stuffed inside a dumpster. But before she can even call for help, a sudden shadow looms in the darkness behind her.

She thought she was just being watched, but the nightmare is already locking her in.
