在一所监狱，彪悍好斗的香月史郎（安藤政信饰）被绳子勒死，与他有暧昧传言的有吉淳在一旁反复叨念是他杀的。警察开始调查这桩奇特的凶案。有吉淳（松田龙平饰）原是一名在GAY吧打工的男妓，遭客人虐待后，将其杀客人，由此被投入牢房。而香月史郎是在不良环境中长大的男子，打死人并和有吉淳在同一天被押入监狱。性格截然相反的他们关系却十分亲密，在狱中香月一直充当着有吉的保护人。有吉发现金字塔和火箭，看见三重彩虹…… 　　囚犯们证词杂乱无章，调查毫无头绪，新调来的监狱长似乎也与这起事件有关，事件的真相藏在迷雾之中。An unknown future. A boy confesses to the murder of another in an all-boy juvenile detention facility. More an exercise in style than storytelling, the story follows two detectives trying to uncover the case. Homosexual tension and explosive violence drives the story which delivers some weird and fascinating visuals.
