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…
With all that Tetsuo's seen, he knows far too much. The gang goes to extreme lengths to ensure Tetsuo's lips are sealed by blackmailing him and getting it all on film. However, the drama club veteran strikes back by making fake footage of Nobuto where it looks like he's still alive…but it's all for naught unless Tetsuo can somehow hack into Nobuto's social media account. With time running out and not many leads to go on, Tetsuo comes face to face with a stranger who wants nothing more than to kill him—and would, if only he knew who he was.
