Veteran New York City police detective Jack Mosley (Bruce Willis) is at the age of retirement, with heart problems and not very agile legs. It's almost 8 in the morning, time for him to change shifts. Just as Jack is about to hand over his duties, he is assigned the task of escorting a criminal from prison to court, which irritates him. The criminal, Eddie (Mos Def), is a chatterbox who drives Jack even crazier with his incessant talking.
