This episode marked the first of several Hitchcock contributions by future Columbo and Murder, She Wrote creators Richard Levinson and William Link. Steve Dunne plays a young man who suffers total amnesia after sustaining a blow to the head. Rummaging through his wallet, the man finds two possible clues to his true identity: a 1,000-dollar bill and a card bearing the name of Dr. Ralph Mannix (Hugh Marlowe). But when he catches up with Mannix, the doctor insists he has never met the man in his life -- though he makes a fateful suggestion as to how our hero can restore his memory.
