Tasked with escorting chatty prosecution witness Eddie Bunker (rapper and seasoned actor Mos Def) from police custody to a nearby courthouse, aging New York City cop Jack Mosley (Bruce Willis) reluctantly gears up for the 16-block trek. But with powerful forces intent on keeping them from reaching their destination, they'll be lucky to make it there alive. David Morse co-stars in director Richard Donner's action thriller.
