Ring of Silence - S4.E6

Emmett Ryker is amongst a group of stagecoach passengers and crew waylaid by and trapped in an isolated cabin by a group of Mexicans from a small cross-border town. The Mexicans want one of the passengers, a cowboy named Wylie (Earl Holliman), for murdering a woman but Emmett believes Wylie should be turned over to the American authorities for a proper hearing. A siege and gun battle ensues but in the end, the Virginian and Trampas, who are waiting for Emmett in a nearby town, come to the rescue of their missing friend.
