U.S. Marshals "Nevada" Jack McKenzie and "Sandy" Hopkins go undercover to bust a gang of stagecoach robbers in this vintage Western serial. Nevada infiltrates the gang, while Sandy works as a cobbler in town, keeping an ear open for local gossip as they try to flush out the inside man tipping off the crooks.
