Banana Joe (Bud Spencer) lives in paradisiacal bliss in a tropical village that is untainted by hard-nosed corporate and bureaucratic types, or by corruption, drugs, gangs, and other ills of modern society. When Banana Joe takes his banana boat to the trading post, he is informed he needs a permit in order to operate the boat. Quite willing to comply with this seemingly simple formality, he treks off to the big city to find this important piece of paper. On his way to obtaining the permit, he runs into television for the first time, crooks as well, and a pretty nifty nightclub singer who greatly opens up his limited knowledge of feminine charms. After more than one contretemps, in which he proves his strength and moral fiber, Banana Joe gets the permit and heads back to the village — only to find that a tacky gambling casino has been set up in his absence. It looks like he has his work cut out for him again, as his shackles rise at this insult to his idyllic home and he gears up for battle. A toe-tapping tropical rhythm lightens the action in the film, aimed for the younger set rather than their parents.
