Dolores, a beautiful, wealthy and paralyzed woman, hires detective Otávio to follow her husband Inácio and find out what his real relationship is with a young woman named Alice. A story of lies, false leads and obscure motivations, in which four characters of dubious morals try to appear honest to each other.

Two straight (but not really) guys invite two naive (but not really) prostitutes for a night of sex. In the preliminary conversations, a little poetry, a lot of philosophy and heavy doses of vulgarity, all with Beethoven in the background. But when it comes to sex, the truth comes out.
