One day, the henchmen of a local gangster boss named Torsillo come ashore in Amantido to initiate the construction a banana processing plant. Of course, Joe (in typical direct-approach manner) evicts the goons, who promptly return to their boss. Torsillo finds out that Joe is trading bananas without a license and decides to exploit it. Upon his next delivery, Joe is apprehended by the police and given the choice of either acquiring a legal license or getting his boat taken away and himself arrested for illegal shipment. Joe travels to the nearest city, which to him is a new world, as he grew up in the rainforest.

Billionaire cousins Bastiano (Terence Hill) and Antonio (Bud Spencer) are two savvy businessmen, at least in one regard. They want to close a large deal, although they have to fear for their lives because of it since their competition won't even stop at murder. Therefore they have an agency find two look-alikes from the United States, stuntman Elliot Vance (Terence Hill) and the jazz saxophonist Greg Wonder (Bud Spencer). These accept the job offer, initially not knowing why they really have been hired. Nonetheless Elliot and Greg manage to fight their way through all kinds of situations without too much trouble. Additionally they quickly come to like the jet-set life. The resulting damage to their reputation provokes the Coimbras to return to Rio ahead of time. This puts them right into the sights of their enemies, alongside the cousins' look-alikes.
