Flight from Memory The Virginian : Season 9 Episode 19

Colonel MacKenzie finds a woman unconscious on a remote mountain trail on the way to visit his hermit friend Muley. He takes her to Muley's cabin and they wait for her to recover as no help is available. She wakes up but is slow to communicate and recover her memory. At the same time another visitor arrives with a lame horse asking to stay until his horse can travel again. As the woman recovers she is attracted to the Colonel in a romantic manner, thinking he is someone she knows, but remembers no details.
