The film begins at a warehouse party with loud music that is attended solely by gangsters. At 2:30 AM, Killer Bean is at a nearby hotel trying to sleep, and makes a phone call asking them to turn down the music. The gangsters refuse, and Killer Bean confronts them. After the gangsters fire a shot at Killer Bean and miss, Killer Bean ends up killing every one of the gangsters in an acrobatic strewn battle. The last bean killed is revealed to be the nephew of Cappuccino, a mob boss.[2]

One police officer, led by Detective Cromwell, investigate the warehouse shootings. The warehouse is known to be owned by Cappuccino, where Detective Cromwell has been trying to convict for years. As the police investigate, Vagan, a lieutenant of Cappuccino arrives at the warehouse. After discovering the massacre, Vagan, who runs guns for Cappuccino, quickly informs his boss what has happened and that Cappuccino is Killer Bean's next target. Due to Killer Bean's skill, Vagan suggests hiring mercenary soldiers to kill him.

Killer Bean receives an encrypted call from his boss warning him that he is being reckless and that the attack on the warehouse should have never happened, and that only the target should be killed. Killer Bean ensures his boss that the mission will succeed. Killer Bean goes to another of Cappuccino's warehouses but instead finds Vagan there, who attempts to kill him. The fight between Vagan and Killer Bean ends in a draw. Vagan leaves a note to Killer Bean which reads, "Shadow Bean, you are too late".
