Successful commodities trader Michael Cromwell (TIM ALLEN), is engaged to marry Charlotte (LOLITA DAVIDOVICH), but first he must finalize his divorce with his estranged wife, Dr. Patricia Cromwell (JoBETH WILLIAMS). Leaving everything behind, including his hyperactive business partner, Richard (MARTIN SHORT), Michael travels deep into the Amazon jungle where Patricia has been living since she left him, and gets the surprise of his life when he discovers he has a 13 year old son, Mimi-Siku (SAM HUNTINGTON), who has been raised among tribesmen. In no time, Michael inadvertently agrees to take Mimi-Siku to visit his own jungle-New York City. Cultures collide and hilarious chaos ensues when Mimi-Siku, who has more skill with blow darts than with social graces, comes to the most sophisticated city on the planet and wreaks comical havoc on his father’s life.
