Have Gun, Will Travel (1957)

S1E37 Silver Convoy

Paladin is tasked with locating James Becker. He follows his trail to Monterey, where he learns that Becker has been imprisoned and sentenced to labor in a silver mine. However, he soon discovers that Becker is reported dead due to a cave-in, or at least that’s what he’s been told. The mine's owner hires Paladin to protect a silver convoy, but before he takes on that responsibility, Paladin decides he needs to investigate the mine further.
