A Las Perlass, ville de jeu du Névada, bandes rivales de Lippy et de Steinberg tiennent les plus beaux établissements de l'endroit. Franck Bradford has hired Jeff Burlington as a comedian, who, to cheer up a difficult audience, launches nightly verbal attacks on Lippy's casino where, he says - the games are rigged. Each of the two gangs sends a henchman to either stop the sarcasm or get in trouble if they don't leave their act as it is. Un certain "Main d'or" qui est autre que Bradford fait attaquer casinos. C'est Jeff, après avoir été kidnappé par les deux bandes devenues amies, quiasquera coupable.
