Now 35, with bad hips, running a failing detective agency with no cases to solve and struggling to pay the rent, he's at a dead end.

In comes a high school girl in his office who says she wants to work with him. With her help, will the out-of-touch, old-fashioned Nagumo get back the fire of his youth?
