The plot revolves around Carlito (Carlos Sanz), who leads a wealthy and influential Mexican-American crime syndicate in Los Angeles. Worried about the encroachment of a group of heavily-armed members of the Chinese mafia, Carlito orders the contract killing of their leader, Don Kim (Keone Young). Carlito's best hitman, a British man called Chev Chelios (Jason Statham), is ordered to do the job. However Carlito underestimated the Chinese and after the hit, the anger of the Chinese is much greater than Carlito expected. Carlito regrets the hit, deeming it "ill-advised", and to ease the pressure Carlito offers the Chinese an explanation and a solution: the hit was nothing to do with him, and Carlito will remove certain elements within his own organization who were responsible and operating on their own.Ricky Verona (Jose Pablo Cantillo), a small time criminal and long-time rival of Chelios, uses the opportunity to conspire with Carlito against Chelios, unknown to Chelios who believes Carlito is still loyal to him. While Chelios sleeps in his apartment one night, Verona breaks in and injects Chelios with the "Beijing Cocktail". This is a synthetic drug which inhibits the flow of adrenaline from the adrenal glands, slowing the heart, and eventually killing the victim. Chelios wakes to find a recorded video explaining that Chelios should only have about an hour left before the poison stops his heart.Chelios phones Doc Miles (Dwight Yoakam) who often works as a personal physician to the Mafia, who informs Chelios that in order to survive and keep his heart beating he must keep his adrenaline pumping through constant excitement and danger, or get some artificial adrenaline, epinephrine. With his own adrenaline keeping the poison at bay at first, Chelios breaks into a hospital and steals numerous drugs, much more than Doc Miles advises him to take and also being "juiced" by hits from a defibrilator. He must keep his adrenaline up through reckless and dangerous acts such as picking fights with other gangsters, stealing things, committing robberies, fighting with police and driving cars through shopping malls.The entire film takes place in a single day. Over the course of the day Chelios sets out to get his revenge on Verona, knowing that he probably will not make it to the end of the day, and attempting to find Verona and his street gang through Chelios' street contact Kaylo (Efren Ramirez), a flamboyant homosexual. Chelios also goes to pick up his girlfriend Eve (Amy Smart) before Verona's thugs get to her. Chelios has sex with Eve in the middle of a busy street in Chinatown while hundreds of people look on, in order to keep his adrenaline up.In the end it is revealed that Chelios spared Don Kim's life and told him to leave LA. Towards the end of the film, Chelios arranges a rooftop meeting with Carlito, Verona and their henchmen, who promise him a fake antidote. Don Kim arrives along with his Triads to assist Chelios, and in a shootout many of Carlito's men are killed. Carlito is killed by an ambitious and treacherous Verona, who then attempts to leave in Carlito's helicopter. The film concludes with Chelios confronting Verona in the helicopter and as they fight the pair fall from the chopper thousands of feet above LA, and mid-flight Chelios breaks Verona's neck. He then calls Eve on his cell phone, apologizing that he will not be coming back to her. Chelios hits a car, bounces off it and lands right in front of the camera. In the last shot it is implied that his adrenaline is indeed still flowing fast; his nostrils flare, he blinks, and two heartbeats are heard.
