To relieve the fatigue of daily life, she visits a hot spring inn for a massage. But it turns out to be a strangely suspicious, carefully laid trap. Her skin, slick with oil, is gently caressed, and her body gradually grows hotter. The masseur's hands, though tender, carry a subtly seductive strength, their warmth slowly stealing away her heart. When the masseur finally moves to touch her body, she finds herself unable to resist—instead, she's drawn completely to his presence. Enthralled by the warmth of his hands, she loses all sense of reason. In that moment, the woman chooses to surrender her body. Each step she takes leads her further down a path from which there is no return.
