M. Night Shyamalan’s latest thriller, ‘Trap,’ revolves around a seemingly ordinary firefighter, Cooper Adams (Josh Harnett), who harbors a dark secret. The film follows Cooper as he attends a concert with his daughter, unaware that he is being hunted by the police for a string of gruesome murders. ‘Trap’ is a wildly implausible and often nonsensical film, but it’s also a darkly entertaining one, thanks to Shyamalan’s signature twists and Harnett’s unsettling performance.
