Emmy nominee Megan Fahey, the breakout star of “The White Lotus” and “The Perfect Couple,” plays Violet, a widowed mother on her first date in years who arrives at a fancy restaurant, where she’s relieved that her date with Henry (It End with Us’ 39 Brandon Sklenar) is more charming and handsome than she expected. But their chemistry begins to fray when Violet begins to be harassed and eventually terrorized by a series of anonymous phone calls. She’s instructed 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 the babysitter. Violet must do exactly as instructed or everyone she loves will die. The final order from her unseen tormentor? Kill Henry.
