This episode is clearly inspired by the famous "Bridey Murphy" affair of the mid-'50s. During a party, Lucy Pryor (Phyllis Thaxter) allows herself to be hypnotized by Professor Miles Farham (Tom Helmore). While in a trance, she regresses to the year 1853 and assumes the personality of a Quaker woman named Dora Evans -- and then, just as Dora Evans had done over 100 years earlier, Lucy promptly murders her husband. During her subsequent trial, Lucy undergoes hypnosis a second time to prove that she had had no control over herself when committing the murder...and the results are astonishing.
