Reservoir Dogs

Six criminals, who don't know each other, are hired by a crime boss, Joe Cabot, to rob a diamond store. They are given fake names so they won't get close and can focus on the job. Confident the heist will succeed, they are caught off guard when the police arrive, leading to a shootout that kills two of them, along with some cops and civilians. When the survivors meet at a warehouse, they start to suspect that one of them is a police officer working undercover.
