A mother who has lived alone with her son since his birth gradually finds her maternal love crossing the line of parenthood. Drawn intensely to her son, she begins to sense the hidden desires deep within his heart. In turn, he responds to her silent longing, resolving to give himself completely. "Mom, I can hear your heart crying out for me! Let's become one—body and soul! I'll wrap you in all the love I have, Mom!" The son embraces his fifties-aged mother, entering a taboo relationship that transcends family bonds. What was meant to be a one-time transgression repeats again and again, gradually transforming the son's feelings. Each step forward forges an entirely new connection between them.
