But for Chev, things are about to get very bad, when he learns he has been injected with a poison called "The Beijing Cocktail" by his rival Ricky Verona, which will kill him if his heart rate drops. Trying to stay alive and seeking help from friends Kaylo and Doc Miles, Chev needs to keep his heart pumping through adrenaline rushes.

Chev fights Verona out of the helicopter and as both of them are falling from the helicopter in the sky, Chev snaps Verona's neck, killing him. As Chev is falling from the sky, he phones his girlfriend, Eve, saying that he won't be coming back ever again. He hangs up and closes his eyes waiting to die.
