For Kenji, a simple convenience store manager who once dreamed of becoming a rock 'n' roll musician, a host of memories from his past come rushing back when one of his childhood friends mysteriously commits suicide. Could this new death be related to the rise of a bizarre new cult that's been implicated in several other murders and disappearances? Determined to dig deeper, Kenji reunites with some of his old buddies in the hope of learning the truth behind it all.
