In the throes of religious fervor, a brother and sister find themselves entwined in a dance of desire that defies their beliefs. Their bodies, slick with sweat and guilt, grind against each other as they struggle to maintain their virtue.

As they collapse, spent and ashamed, they cling to each other, their hearts pounding with the knowledge that they have crossed a line from which there is no return.
