Dwelling on his past glory as a prize-winning author, Ryota wastes the money he makes as a private detective on gambling and can barely pay child support. After the death of his father, his aging mother and beautiful ex-wife seem to be moving on with their lives. Renewing contact with his initially distrusting family, Ryota struggles to take back control of his existence and to find a lasting place in the life of his young son - until a stormy summer night offers them a chance to truly bond again.
A Japanese couple stuck with part-time jobs and hence inadequate incomes avail themselves of the fruits of shoplifting to make ends meet. They are not alone in this behaviour. The younger and the older of the household are in on the act. The unusual routine is about to change from care-free and matter-of-fact to something more dramatic, however, as the couple open their doors to a beleaguered teenager. The reasons for the family and friends' habit and their motivations come under the microscope.
