S01E37 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.
