The Virginian S02E11 - The Fatal Journey

After she calls for the President to bring in the army to rid the badlands of outlaws, newspaper editor Molly Wood, the Virginian's love interest, is murdered by four of those outlaws: O'Dell (Steve Ihnat), Horn (John Milford), Denver (Berkeley Harris) and their ruthless leader, Colonel Calhoun (Robert Lansing). The Virginian joins a posse but while the other posse members give up he eventually locates the villains' badlands hideout. He poses as a prison escapee, joins the gang and exacts his revenge.
