While riding shotgun to protect a valuable gold shipment, Hardie and his stagecoach driver have an interesting collection of passengers and cargo:a U.S. Army officer being sent to Fort Laramie to stand trial, a married couple and a baby.

During an attempted hold-up, Hardie guns down a man who the outlaw leader claims was not a member of their gang. Hardie learns the man was an ex-convict who had gone straight after being released from prison and investigates him.
