Carrying two passengers and money for the local bank, the stage to Cooper's Creek left Tombstone and never arrived - it just vanished. Cooper's Creek becomes the scene of shootouts, and Marshal Willard, accompanied by a young investigator, is soon headed for a deserted mining town. They find what they are looking for, except for one missing parcel. Only an old miner can tell them what happened - but can they track him down and get him to talk?
