In Joel Schumacher's taut thriller, told in real time, cynical, smarmy PR man Stu Shepard picks up a ringing phone in a booth in a busy New York street to find a killer on the line. Armed with a high-powered sniper's rifle, the anonymous caller soon proves his prowess and presents Shepard with a choice: convince the police of his story before they shoot him or drop the phone and be shot. His only hope lies in self-abasement and facing up to the truths of his life. Starring Colin Farrell and Katie Holmes.
