The Virginian - Season 8 Episode 2 A Flash of Darkness

During a cattle drive, a rattler startles the Virginian's horse while he is chasing a stray, and he is thrown and hits his head on a rock causing temperary blindness. As he wanders in the darkness, he stumbles upon a young lady who lives with her father (James Whitmore)and brother, whom the Virginian had just fired. The daughter wants to help the Virginian though the men protest. The two men tell her that they are returning the blind man to his friends but actually plan to kill him. After leaving the house, the Virginian somehow manages to escape and makes it back to the house where he wanders into the corral and is nearly trampled by the horses until Trampas and Jim Horn rescues him from the corral and the two men.
