Satoshi Isaka follows up on his taut media thriller Hasen no Marisu with this comic thriller about the perfect crime gone horribly wrong. A hard-up locksmith (Kenichi Hagiwara) and a vengeful computer nerd (Kazuma Suzuki) meet online, adopting the monikers Key and Gun respectively. Together they hatch a perfect heist against a consulting company -- Gun's former employer. At first everything goes perfectly. Gun's expert hacking from his laptop and Key's veteran touch quickly open the safe. Unfortunately, an overzealous security guard makes an unscheduled visit. After dispatching him, the two flee to the closest elevator, only to get stuck between the eighth and ninth floors.
