Cole Cash (also known as Grifter) is what you might call an arms enthusiast. Paul Newman (not that Paul Newman) is an anti-gun activist. Both are in Vegas for a firearms convention, and each is looking to disrupt the show for his own reason -- Newman wants to wipe firearms off the face of the earth, and Cash wants to steal a state-of-the-art armament known as the Probability Annihilator. Cash has got a dead-accurate eye -- perhaps the best in the world -- to back up his play, but Newman's got something that'll outfire any ol' weapon! Newman's got . . . The Mask!
