In “Trap,” Hartnett plays a dad bringing his daughter to a pop concert at a local arena. She’s jazzed to see Lady Raven (Shyamalan’s daughter, Saleka Shyamalan, plays the star and wrote new songs for the soundtrack) and he’s happy that she’s happy. (There will be countless flashbacks to girl dads bringing their daughters to Taylor Swift last summer.) During the show, however, he starts to notice an alarming police presence, seemingly there to capture a notorious serial killer known as The Butcher. The Shyamalanian twist? Hartnett is the serial killer. How cool is that?
