Jim Hardie arrives in Calico with three other passengers including the young lad Pete Bridger who is met at the station by his Grandpa Bridger who is a wood chopper. The other two passengers go to the saloon to wait for the trip to continue while Jim meets with the local agent, Mr. Bennett. There is a new stage line in town called Mountain Stage Line which is using intimidation to force the riders to drop Wells Fargo for their own line. Bart Dillon runs it using two henchmen as enforcers. Jim is there to stop them but he finds his job complicated by Grandpa Bridger who tells some really big whoppers to impress Pete. This includes him being a Pinkerton agent and an outlaw. His fake attempt to break into a broken safe is broken up by someone else trying to rob the real safe. When Pete learns the truth from Grandma Bridger, Grandpa goes to the extreme to regain Pete's love.
