The Virginian (1962)

S3E19 Six Graves at Cripple Creek

Emmett Ryker discovers that McMasters, the man responsible for the deaths of his close friends—a rancher and his daughter—two years prior, is among six individuals thought to have been killed by Indians. Convinced that McMasters is still alive and eager for revenge, he teams up with Lucille Carver (Sheilah Wells), whose father was also believed to be a victim, to journey to the massacre site at Cripple Creek. Their investigation leads them to Deadwood, where Emmett suspects a gold prospector may actually be McMasters, and possibly Lucille's father.
