In this high-tech thriller from Japan, a computer programmer is edged out of the firm he helped to found just in time for his former employees to strike it big with the technology he created. Eager for revenge, the programmer makes plans to break into the offices and steal his fair share of the windfall. Needing someone who can crack a lock, the programmer, calling himself Gun, puts out feelers on the Internet, and eventually joins forces with a safecracker named Key. Mutual suspicion puts Gun's plan in danger almost from the start, and matters only get worse when the pair find themselves trapped inside an elevator stuck between floors.
