Tetsuo Tosu is a typical father whose biggest worries are his job and his rebellious daughter, Reika. That is, until he finds a bruise on her face. His worst fears come true when he finds out she has a secret boyfriend…and he’s part of a crime ring that’s using her to steal her grandparent’s wealth. If that wasn’t bad enough, the thug catches Tetsuo snooping around and threatens to kill Reika as soon as she gets home. Fueled by fatherly instincts, Tetsuo murders the man…only for his wife to walk in and witness what he’s done. Now with a corpse to hide and a crime ring hot on his tail, Tetsuo must resort to his love of detective novels and his wits to stay one step ahead of a grim fate…
Concerned for his daughter, Tetsuo tags along on her date with two boys in hopes one of them will be around to protect her if he’s sent to prison. Little does he know that one of them works for the gang…and both of them know what he’s done. Increasingly desperate as the gang ramps up the violence in their plans surrounding Reika, Tetsuo considers handing himself in to the police…until an unexpected ally promises to help take down the gang once and for all.
