Celebrated madam and advice columnist Xaviera Hollander (Joey Heatherton) is called to testify as a hostile witness in a senate hearing/crusade against loose morals. It seems that the Senators are about to be implicated into a widespread sex scandal regarding a hooker friend of Xaviera's, who has conveniently disappeared. Their plan to use her well-publicized sexual exploits to make her a scapegoat backfires when her irreverent testimony charges the otherwise lifeless proceedings. Before the end of the hearings, an undercover CIA agent convinces her to serve her country by seducing an important Arab oil sheik, where she discovers her friend in the harem. Upon her return, she discredits the Senate sub-committee and exposes them as perverts and white slavers, making America safe for erotic sex workers.
