Eight men eat breakfast at a Los Angeles diner before their planned diamond heist. Six of them use aliases: Mr. Blonde, Mr. Blue, Mr. Brown, Mr. Orange, Mr. Pink, and Mr. White. The others are mob boss Joe Cabot, the organizer of the heist, and his son and underboss, “Nice Guy” Eddie Cabot.
After the heist, White drives Orange to the rendezvous, an empty warehouse. Orange is bleeding profusely from a gunshot wound. Pink arrives, agitated; he believes the job was a setup and that the police had the diamond store staked out. White tells Pink that Brown was killed while escaping and that Blue is presumed dead. They discuss Blonde, who murdered several civilians during the heist; White is angry that Joe, an old friend, employed such a “psychopath”. Pink reveals that he escaped with the diamonds and hid them in a secure location. They argue over whether to take the unconscious Orange to a hospital.
