The Great Showman

Dr. Spout, a carnival snake-oil salesman, arrives in Dawson with his dog Trickster, and they con people into buying a miracle cure all elixir. Trickster becomes friends with White Fang, and he decides to run away to live in the wild. When Beauty finds out there is a reward for Dr. Spout's capture, he riles up a crowd, which heads out to find Dr. Spout. Trickster must help save his old friend and master or stay free in the wild. White Fang decides to help. After Trickster is reunited with his master, Dr. Spout, along with Trickster, leaves on the next steamboat and returns the money, vowing never to cheat again- at least not until he gets to the next town.
