When Toru Narazaki's girlfriend, Ryoko Tachibana, disappears, he tries to track her down despite the warnings of the private detective he's hired to find her. Ryoko's past is shrouded in mystery, but the one concrete clue to her whereabouts is a previous address in the heart of Tokyo. She lived in a compound with a group that seems to be a cult led by a charismatic guru with a revisionist Buddhist scheme of life, death, and society. Narazaki plunges into the secretive world of the cult, but he has no idea of the bubbling violence he is stepping into.
