In the heart of Rio, two innocent siblings, drawn together by the pulsating rhythms of Carnival, find themselves in a cramped closet, their bodies pressed close. The air is thick with desire and the scent of sweat as they tentatively explore each other's virgin flesh.

They struggle with their religious upbringing, but the primal beat of the drums outside echoes their forbidden yearning.
