When circus owner Max Sabatini dies, he leaves five million dollars to his son Foster. But there is a catch. To get the money, Foster has to take care of Max's three orangutans for a minimum of five years. This stipulation proves to be too much for Foster's girlfriend Cynthia who lives with him, and her mother seizes the opportunity to convince her to move out. In addition to this problem, the Zoological Society, who will get the money if Foster fails, sends some mobsters to cause him even more trouble.
