The best Enzo Garinei’s action movies

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.

By day, Ovidio (Joe Dallesandro) and his two friends work at a data center. After work, they blow off steam by committing random acts of savage violence, swiftly graduating from sparking a riot at a football game to vehicle theft, rape, and murder. The police are convinced this recent spate of crimes is politically motivated, but world-weary veteran Commissario Santaga (Enrico Maria Salerno) suspects a far more terrifying explanation: that these young men are motivated by nothing more than boredom and disaffection at civilized society. As Ovidio's behavior escalates, a psychological game of cat-and-mouse ensues between the two adversaries, building towards a shocking final confrontation.

When the eyewitness to a brutal murder decides not to testify, the actual murderer chooses to finger him as the murderer and claim eyewitness status for himself.
