Three friends from a club are held captive by an unknown assailant. The culprit issues a series of commands that seem to test their friendship: tell each other about their family backgrounds, tear off their fingernails, and gouge out their eyes. The demands gradually escalate, and a change occurs in the relationship between the leader-type Kohei, the wealthy and handsome Takumi, and the jokester Shota. Furthermore, sins that were supposed to be buried are exposed... The kill-or-be-killed death game begins now.
