Alias Smith and Jones (1971)

S2E8 Night of the Red Dog

Heyes, the Kid, and a few other men watch as an elderly man collapses under the weight of his gold. A doctor informs him he's nearing death, prompting the man to unveil a map of his mining claim, which he entrusts to the group. They head to the site and begin digging, but tensions flare when their gold goes missing—not once, but twice. Things take a turn for the worse as snow blankets their cabin, forcing them to endure the winter together. This leads to a high-stakes poker game, where trust becomes a dangerous game for both Heyes and the Kid.
