George Hilton, Edd Byrnes and George Martin play 3 thieves who chase a much more successful thief: Major Lloyd (Gerard Herter) who stole a wagon-load of gold from the confederate army. As soon as he moves into the borderland, Mexican bandits are also attracted by the yellow metal. So much black powder was spent during the making of this movie, apparently, that you could make three westerns with it, but in between all the shooting and countless explosions, "Professionisti per un massacro" displays a certain sense of humor. It is a spaghetti western of the kind that likes to play with the rituals typical for the genre, using coffins and machine guns, and if you like this sort of thing, you'll find the movie easy to sit through... even if it is nothing surprisingly new.
