In the dim light of their shared bedroom, a pious sister and brother, both virgins, find themselves alone and restless. The sister, overcome with religious fervor, decides to verify her purity by filming herself. She begins to undress, her eyes closed in prayer, revealing her untouched body. As she reaches for the camera, her brother enters, startled to find her in such a state. He watches, frozen, as she tentatively touches her breasts, her stomach, her thighs, her fingers brushing against her virgin lips. The camera captures her innocence, her guilt, her struggle between faith and flesh.
