The film has been released under various names including Trinity Rides Again, Nobody's The Greatest, and A Genius, Two Friends and an Idiot in order to capitalize on other previous and more-successful Spaghetti Westerns that starred Terence Hill, namely My Name Is Nobody and They Call Me Trinity and Trinity Is Still My Name.
Joe Thanks (Terence Hill) is a genius conman. He conducts various schemes with his two friends: Half-breed Steam Engine Bill (Robert Charlebois) and his girlfriend Lucy (Miou-Miou). Lucy loves both men, and they in turn both vie for her affection.
Joe formulates an extremely elaborate plan to steal $300,000 from Major Cabot (Patrick McGoohan), an Indian-hating cavalry man, and in doing so save the Indian land he is trying to steal. Every time the plan seems to be failing, Joe has another trick up his sleeve. The movie climaxes with a stagecoach chase and a gigantic explosion.
