Emmy-nominated Megan Fahey, a rising star of The White Lotus and The Perfect Couple, plays Violet, a widowed mother on her first date in years who arrives at an upscale restaurant to her relief, finding her date, Henry (Brandon Sklenar of It Ends with Us), more charming and attractive than she expected. But their chemistry falters as Violet becomes increasingly irritable and 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 security cameras will kill Violet’s young son and her sister, a nanny. Violet must do exactly as she is told or everyone she loves will die. Her unseen tormentor’s final instruction? Kill Henry.
