In the dimly lit, old-world charm of Rio de Janeiro, Sraoculta and Sroculto, two siblings with a shared secret, find themselves drawn to each other in ways they shouldn't. Sraoculta, a sultry brunette with a penchant for lace, teases her brother with glimpses of her ample cleavage and pert bottom, while Sroculto, a strapping young man with a perpetual five o'clock shadow, struggles to keep his eyes - and hands - to himself. Their dance of desire takes them from the bustling streets of Rio to the intimate confines of their shared apartment, where they explore the boundaries of their forbidden love.
