4 for Texas

When con men Zack Thomas (Frank Sinatra) and Joe Jarrett (Dean Martin) team up to open a gambling den, they quickly realize that business in the wild West isn't so easy. Both miscreant banker Harvey Burden (Victor Buono) and loose-cannon gunman Matson (Charles Bronson) are out to stifle Zack and Joe's moneymaking schemes. Luckily, the grifters still find plenty of time to romance a couple of voluptuous frontier babes (Anita Ekberg and Ursula Andress). (official distributor synopsis)
