Their visit results in their phone service getting cut off. Homer tries to steal phone service, but gets electrocuted for his trouble. Lisa confesses to making the call and tells them of the donations she'd made for an orphan boy named Renaldo in Brazil, with whom she'd lost contact with. The family decides to make a trip to Brazil to find him. The family flies down to Rio, as Maggie takes care of herself, under the watchful eyes of Patty and Selma. They split up with Lisa and Marge looking on one side of town and Homer and Bart on the other. Homer gets kidnapped when he gets into an unlicensed taxi. The kidnappers take Homer up the Amazon. Marge reports the kidnapping to an uncaring police department and Homer tries to raise the $50,000 on his own. Lisa finds Renaldo working for the kids show that Bart has watched with great sexual interest since arriving in Rio. Renaldo is now wealthy, thanks to the new dancing shoes Lisa's donation purchased for him, so he gives Lisa the $50,000 that will let them get Homer from the kidnappers. The transfer is made and Homer is returned, but as we leave our friends in Rio, Bart is celebrating Carnival in the belly of a snake.
