The very "hot" party organized by Jack Vernier for the release of his novel "Orgasms under bombs" just finished. He then discovers that Liza, the au pair girl apparently nice and quiet who lives in his house, was murdered. Mike, a detective, interrogates every person who attended the party. Very soon, it appears Liza actually had perverse sexual relations with several guests during the night and the preceding day. Would innocent Liza have in fact been a nymphomaniac adventurer taking profit out of her vain affairs with influent people? And then, who could have murdered her and why? Only the parrot knows the truth.
