So Sing Wah, a former lead singer of the band, fell into the trough of marriage and career in middle age. He met his ex-girlfriend Ha Man Huen in the hospital. Recalling the love in the midsummer, she now has natural grace and elegance. But it is a pity that she left without leaving any contact. Unexpectedly, there is a bad new from her after half a year; it would be her smiling face in the photo in the mourning hall when meeting her again. So thought that everything now has become the past, but a week later, an uninvited guest came to him. Sonia, a fifteen-year-old girl claimed to be daughter of Ha Man Huen and have a presumptuous request. Ha Man Huen entrusted the lawyer before her death, hoping that So and Sonia would scatter the ashes under the Bodhidharma sun to make up for the regret of breaking up that year. The two lonely people with thirty years apart, hugged the ashes and finally decided to go to Japan together.
