Dwelling on his past glory as a prize-winning author, Ryota (Hiroshi Abe) 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 (Kirin Kiki) and beautiful ex-wife (Yoko Make) 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 (Taiyo Yoshizawa) - until a stormy summer night offers them a chance to truly bond again.
