Naïve, good-hearted fish tank cleaner, Deuce Bigalow thought his career as a gigolo was over. But just when he thought he was out--T.J. Hicks pulls him back in. Deuce is seduced back to his unlikely pleasure-for-pay profession when Hicks, his former pimp, is implicated in the murders of Europe's greatest gigolos. Now Deuce must go back "undercover" in order to clear the name of his good friend. Along the way, he must compete against the powerful European Union of prostidudes (The Man-Whore Society) and court yet another bevy of unusual female clients, including the beautiful Eva, who suffers from acute obsessive-compulsive disorder.
