Who hasn't dreamt of returning to childhood? Hiroshi Nakahara is a forty-something salaryman returning to Tokyo from an intense business trip. Tired and hungover as he boards his train, he awakens to discover he is traveling back to the town of his upbringing, not Tokyo. Memories of his mother surface as he realizes he is now the same age as she was when she died. Arriving in Kurayoshi, drawn through his distant neighborhood to the cemetery and his mother's grave, he is transported back into his 14 year-old life and body while retaining all his adult character and experiences. That day his father disappeared without explanation, the death of his mother, will he change his past or be forever condemned to relive each painful moment? And will he ever see his wife and daughters again?
