Taeko and her husband, Jiro, are living a peaceful existence with son, Keita. A tragic accident brings the boy's father, Park, back into her life. Taeko throws herself into helping this deaf and homeless man to cope with pain and guilt.

A couple seem happy and fulfilled personally and vocationally as they live their ordinary lives, work their jobs and raise their son. A routine birthday party becomes the catalyst for complications, however, as the past encroaches on the present. The family members past lives and everyone's current feelings for the others become risk factors suddenly in what would have been an otherwise uneventful path to the future.—aghaemi
