Based on the 1960s cartoon of the same name. Dudley Do-right, a Royal Canadian Mountie, is busy keeping the peace in his small mountain town when his old rival, Snidely Whiplash, devises a plan to buy all the property in town and then start a phony gold rush by seeding the river with gold nuggets. Can Whiplash's evil plan be thwarted by this well-meaning (but completely inept) Mountie?
