昭和55年、ある廃ビルで、質屋の店主が殺される事件が発生。決定的な証拠が不十分のまま、警察の捜査は打ち切られるが、担当刑事の笹垣は、ガス中毒死をとげた容疑者、西本文代の10歳の娘である雪穂の妙に大人びた態度と、被害者の息子でどこか暗い目をした10歳の少年・亮司の姿が脳裏に焼き付き、妙な割り切れなさを覚える。それから歳月は流れ、大人に成長した雪穂と亮司の周囲で、再び不可解な事件が続発するようになる。

A detective investigates a series of murders. A possible serial killer might be on a rampage, since they all are in the same vicinity and by the same method, but as the evidence points toward the detective as the prime suspect, a ghost in red follows him, and he begins to question his identity. His realization of what seems to have really happened results in something much more sinister and larger in scope, and it leaves his psyche scarred.

Tenshu is imprisoned and sentenced to death for murdering the men who raped his girlfriend. However, he manages to survive his execution and is presented with an option: face another execution attempt or subject himself to their bizarre and dangerous experiments.
