Plot synopsis: An old saying has it that it takes the first generation to create the business and the second one to destroy it. When the Tanaka Family's father, a career private eye, passes away, eldest daughter and mother figure Sayuri has to decide whether or not to continue the family detective business. Seeing no hope or interest on the part of her other younger siblings to carry on the business, she is about to shut it down when her long-lost elder brother, Ichiro, returns. A down-on-his-luck truck-driving single father now, he decides to take the mantle and continue the family tradition-his only experience being that he played cops and robbers as a kid. In his new capacity of "president" of the family business, he conveniently decides to move into the home that he left many years before. Will the Tanaka Clan really be able to resurrect the business together? Or does elder brother Ichiro have some other plans for the business?
