Bonanza - Season 13 - Eps 21: Search in Limbo
Sid Langley is a real estate broker who is not well liked in Nevada, thanks to his shady ways of doing business. An irritable Ben is barely polite with Langley when closing a land transaction. However, things soon get worse than that headache and blurred vision Ben suffers from when he learns that Langley has been critically wounded by an unknown assailant. Ben, who somehow can't remember the past 24 hours, fears he may have been the gunman and tries to reconstruct the activities of the past day to prove his innocence.
