When Deuce Bigalow (Rob Schneider), a naive, good-hearted fish tank cleaner, loses his job at the Los Angeles Aquarium, his life changes dramatically when he is hired to clean the Koi pond at a luxury Malibu apartment complex. He crosses paths with the debonair Antoine Laconte (Oded Fehr), world class gigolo who asks Duece to house-sit to care for a sick exotic fish while he is away on business.

As Deuce gets comfortable at Antoine’s place, he sets off a chain of events that virtually destroys the apartment, primarily Antoine’s $6,000 custom-made Living Color aquarium. 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.
