Deuce Bigalow is a naive, good-hearted fish tank cleaner, who is very dedicated and happy with his work. His only dream is to take his fish and move out of his bad neighborhood to the beach- to be close to his 'friends' in the ocean. After he loses his job at the Los Angeles Aquarium, his life changes dramatically. Deuce crosses paths with the debonair Antoine Laconte, world class gigolo. Antoine has the life any man would want- fancy cars, beautiful women and, most importantly for Deuce, a state of the art aquarium. When Antoine's lionfish comes down with a potentially fatal gill disorder and he has to go away on 'business,' Antoine asks if Deuce will stay at his apartment. As Deuce gets comfortable at Antoine' place, he sets off a chain of events that virtually destroys the apartment. Needing money to pay for the damages, and after 'accidentally' answering Antoine's business phone, Deuce launches his new career as a gigolo. He quickly enters a world beyond his wildest dreams.
