Megan Faye, an Emmy Award nominee and star of The White Lotus and The Perfect Couple, plays Violet, a widowed mother who goes on her first date in years. She arrives at a high-class restaurant, where she is relieved to discover that her companion, Henry (Brandon Sklenar from “It All Ends With Us”), is more charming and handsome than she expected. But their chemistry begins to fade when Violet begins to get irritated and then terrorized by a series of anonymous messages on her phone. She is told not to tell anyone and to follow instructions, or the hooded figure she sees on her home’s surveillance cameras will kill Violet’s young son and her sister, who is watching over her. Violet must do exactly what she is told, otherwise everyone she loves will die. The last order of his invisible tormentor? Kill Henry.
