Four years after losing her husband, Kotoe lives as a widow, quietly going through each day. The elderly men in her neighborhood association, drawn to her pure and innocent nature, grow concerned about her living alone. Unable to suppress their hidden desires, they drug her with a special sleeping potion. Even after the effects wear off, the neighborhood chairman cannot forget the warmth of her body and soon administers another sedative to have her again. Waking in a daze between dreams and reality, Kotoe becomes aware of the men's feelings toward her, and unfamiliar emotions begin to stir within her. "The Big-Titted Widow Raped While Asleep," originally created by married-woman fetish author Toui Hitori, is brought to life in its first live-action adaptation starring popular actress Ai Sayama. As the desires of the neighborhood men entwine with Kotoe's own awakening sensuality, a new and intense drama unfolds.
