In Bangkok, in a low-budget hotel called "Heaven", the fate of four guests are interconnected due to a theft in a room: Sean, a paranoid English drug dealer, that is dealing with a powerful local drug lord; the also British psychologist Rosa, who is grieving the loss of her son and making a research with poor children in Thailand; a seriously wounded killer, hired to kill the mobster; and Wit, a thirteen years old abused bellboy, that steals the guests.
