The Man from Button Willow is a 1965 American animated Western film about the adventures of Justin Eagle, the first U.S. government agent.

Justin returns from business in San Francisco, reuniting with his adopted Japanese daughter Stormy and ranch hand Jeremiah "Sorry" Baker.

The foal escapes the ranch and goes up a nearby mountain, accompanied by Justin's dog Shady and pet skunk, Alfie.

Justin learns from general store proprietor Abner Hawkins that several settlers have recently had their homes burned and been chased off their land, and that Senator Freeman is in San Francisco to investigate.

Starting a fight as cover, Justin follows Kelly but falls through a trap door into a rowboat and is himself shanghaied by a ship captain.
