A religious retreat takes a sinful turn when a pair of innocent siblings, haunted by their secret desires, find themselves alone in the dimly lit chapel. The scent of incense and the echoes of hymns still linger, but the siblings' minds are filled with profane thoughts. They resist, their faith warring with their flesh, but the tension becomes unbearable. Slowly, they give in, their bodies pressing together, their hands exploring forbidden territories. Their moans fill the chapel, drowning out the memory of hymns, as they lose themselves in a heated, taboo embrace, their bodies slick with sweat and sin.
