It's Christmas Eve in Tokyo as Ichiro is moving into his new apartment one month ahead of schedule. As he is getting settled in, two strangers enter the apartment and are surprised to find him there.

Three people find themselves locked in the same room: a skilled hitman awaiting execution for having an affair with a yakuza boss's woman; a "trigger man" from a rival gang who has been taken prisoner; and the boss's mistress—the very woman who seduced the hitman. Amidst the confinement, they trade insults and deceive one another, yet eventually, they become bound together by a shared desire for revenge...
