Bruce Willis stars as NYPD detective Jack Mosley, a cop assigned to drive petty criminal Eddie Bunker to testify. It should be a simple task. It should take 15 minutes. But a routine errand becomes a fight for survival that will change two men forever in 16 blocks. Out of shape, with a bad leg and a serious drinking problem, Jack (Willis--Sin City, The Sixth Sense) has a simple role on the force--clock in, clock out and stay out of trouble in between. When Jack shoves Eddie Bunker (Mos Def--Lackawanna Blues, Monster's Ball) into the back of his car, he doesn't notice the van looming behind them. Jack stops Eddie's execution, killing one assassin, but when Jack calls for backup, homicide detective Frank Nugent (David Morse--Hearts in Atlantis, The Green Mile) is the first to arrive at the scene. Eddie suddenly goes pale--one of the detectives on Nugent's team is the man against whom he is supposed to testify.
