Autumn Rain delves into the dark heart of sibling lust. Two devout siblings, haunted by religious guilt, find solace in each other's arms. In a secret, cramped space, they shed their inhibitions, their bodies responding to the forbidden touch. As they give in to their taboo desires, they are consumed by a primal, aghori passion. But as their bodies entwine, so too do their souls, bound by a sin they can neither resist nor regret.
