Ep 5. Bahama Mama

After the Smith family's usual Sunday breakfast in their backyard, Roger asks the family if anyone wants to go to the Bahamas with him. When no one volunteers, Roger lies to the family, telling them there is a family reunion happening in the Bahamas and that they need to go. Reluctant at first, the Smiths eventually agree to come with Roger on a luxurious vacation in the Bahamas.

Upon arriving in the Bahamas, the family finds out that Roger has been lying to them and that they are not attending a family reunion. Instead, Roger has been using them for his personal gain and has used the family's trust to swindle money out of them. The Smith family is disappointed, but luckily, they meet a woman named Nagaina who takes pity on them and shows them around the island.

In the meantime, Roger becomes infatuated with Nagaina and begins to fall for her. Despite his love for her, Roger continues to scheme to make money and tries to steal from her wealthy husband, Prince Rogercopulus. Roger disguises himself as a Bahamian woman and, with the help of Klaus, steals a large diamond from the Prince's mansion.

Back at their hotel, the Smith family and Nagaina find themselves in trouble when they are caught with the diamond by a group of thieves who are also after the valuable object. The group of thieves takes the diamond, and the family is left stranded on the island with no money or a way back home.

Desperate to get their diamond back, the family devises a plan to sneak into the thieves' lair and steal back the diamond. With the help of Nagaina, the Smiths are able to retrieve the diamond and return it to Prince Rogercopulus in exchange for enough money to fly them all back home.

In the end, Roger realizes that his love for Nagaina is selfish, and he lets her go so that she can return home to be with her husband. The Smith family returns home, happy to be back, grateful for the adventure, and cautiously wary of Roger's schemes.
