Teresa is a nurse and does not have an easy life: her husband plays poker and next to her she sleeps only and the father organizes the illegal lot among the sick. So one night Teresa is involved, in spite of herself, in a whirlwind of ambiguous situations, together with Ferdinando and Friariello, met by chance, between camorristi, dog races and a bingo of which he unknowingly becomes the prize. But “has to pass” to “nuttata”, this is certain, but how?

Bud Spencer plays Banana Joe, a brawny yet friendly man who lives in a small rainforest village called Amantido with a huge number of his own children and regularly delivers bananas to a South American river port (hence his name). 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.
