The head of Ranch Security is again called to duty--this time to arrest the marauding trespassers who are threatening to stampede the cattle. Join Hank as he tracks down enemy agent Mysterious Esther, gets a surprise visit from pretty Miss Viola, attempts a daring escape from the relentless Vampire Vacuum Sweeper, almost single-handedly reprimands town dog Buster and his gang of thugs and sustains the ranch through another dangerous night.
