Kidd Mane is a lion cub without a home - that is, until he wanders into the western settlement of Tuckerville, which happens to be a town without a sheriff. Meeting folks and making friends, Kidd applies for the job and, with a little help from the long-suffering town council - Judge Ryker, Miss Scarlet, and Miss Clarabelle - he becomes the new sheriff of Tuckerville!

When Tuckerville's sheriff Kidd Mane gets back from vacation, he finds himself out of a job and the whole town up in arms: The town's mayor, Mr. Tucker has given Kidd's sheriff badge to a dumb T-Rex named Cliff and intends to turn Tuckerville into a circus with all its inhabitants as main attractions. Will Kidd Mane reclaim his town and return peace and quiet to Tuckerville?
