Phone Booth (2003)

A phone call can change your life, but for one man it can also end it. Set entirely within and around the confines of a New York City phone booth, thriller follows Stu Shepard, a low-rent media consultant who is trapped after being told by a caller - a serial killer with a sniper rifle - that he'll be shot dead if he hangs up. A sudden and shocking act of violence near the booth draws the attention of the police, who arrive backed with a small army of sharpshooters. They believe that Stu, not the unseen caller of whom they remain unaware, is the dangerous man with a gun. The senior officer on the scene, Captain Ramey, tries to talk Stu out of the booth. But unbeknownst to Ramey, his team, the media circus that has flocked to the site - and Stu's wife, Kelly, and his client /prospective girlfriend, Pamela - the caller has them all in his high-powered rifle sights. As afternoon turns into evening, Stu, the embodiment of an unethical, self-serving existence, must now undertake a sudden and unexpected moral evolution. He is emotionally stripped naked by the caller. Stu's lies, half-truths, and obfuscation no longer matter. Instead, he must dig deep into his soul, find his strength and attempt to outwit the caller, taking the game to an even more dangerous level.
