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...
