A man finds the son he never knew he had, and a boy discovers a city he never knew existed, in this comedy. Michael Cromwell (Tim Allen) is a commodities broker who deals in coffee beans; while on a trip to Brazil, Michael is abandoned by his wife, Patricia (JoBeth Williams), an anthropologist who decides to stay behind to study the indigenous tribespeople of the area. Fourteen years later, Michael has decided to marry his new girlfriend, Charlotte (Lolita Davidovich), but since he never formally divorced Patricia, he must go to Brazil, find her, and get her to sign a divorce agreement. Once he arrives, he discovers that there's a bit of a complication -- Patricia was pregnant at the time she left Michael, and she is now the mother of a 13-year-old son, Mimi-Siku (Sam Huntington). Mimi-Siku is about to undergo the manhood rituals of the tribe that adopted Patricia and himself, and when the leader discovers that the boy's father has arrived, he insists that Mimi-Siku should return to the "Stone Island" of Manhattan to get to know his dad. Arriving in New York City with a loincloth and a blowgun, Mimi-Siku has a lot to learn about living in contemporary America. Charlotte is not too happy about discovering that she's about to be a stepmother, while Richard (Martin Short), Michael's business partner, wishes the boy wouldn't eat the tropical fish from his aquarium. Jungle 2 Jungle is an Americanized remake of the French comedy Un Indien Dans la Ville.
