Set in 1964, He Went That Way is a taut thriller based on a true crime story that puts a wicked spin on the buddy road trip film. The film follows 19-year-old serial killer Bobby (Jacob Elordi) as he is picked up by a celebrity animal handler, Jim (Zachary Quinto), on a desolate stretch of Route 66 with priceless cargo in tow: Jim's chimpanzee, Spanky, an American TV darling. As stress between Bobby and Jim rises and their fiery personalities combust, the road only becomes more treacherous the farther they go.
