The Mob are trying to bypass the system any way they can. Along come two nice guys, a wrestler (super-strong Bud Spencer) and ice-cream vendor (Giuliano Gemma) who are mistaken for dangerous killers by Mafia Man "Sorriso". Gemma is told by the gangsters to persuade 'The Mystery Man' Bud Spencer to take a dive in a match. The unsavoury hoods are ignorant, remorseless and childish criminals who don't comprehend the enormity of their transgressions. So "Spencer" deals with them in his own havoc-wreaking way...don't miss the martial arts sequence!
