The Son of Davy Crockett

Young Dave Crockett and his sidekick Cannonball find themselves on the trail of water-hole poisoners in the territory known as The Yucca Strip which, through a surveying error, is neither part of the United States nor Indian Territory. King Canfield, self-appointed ruler of the strip, is determined to see that the residents can't vote themselves into the Union through an honest election. (imdb)
