I am looking for a title of an episode where a man falls in love with a beautiful woman that has a ribbon around her neck that he despises. I cuts the ribbon off while she sleeps and her head falls to the ground and then she says something back to the man.

Thanks
Dan

This could be one of two episodes.

The first:

0895 Wed, 9/20/1978 The Beheading

Teri Keane
Grace Matthews
Court Benson
Bryna Raeburn
Elspeth Eric

A woman recounts how she became the world's first head transplant recipient.

or this one:

0039 Sat, 2/16/1974 A Lady Never Loses Her Head

Kim Hunter
Nick Pryor
Bryna Raeburn
Ian Martin
Court Benson
Ian Martin

A newly married woman is haunted by a headless ghost that bears a remarkable resemblance to her.

Thanks, but neither one of those episodes is the one that I was thinking about.

Anyone else have an idea?

Yes... I believe you are thinking about a 1979 episode called The Guilliotine. It is an adaptation of the Washington Irving horror story called Tale of the German Student. It takes place during the reign of terror! The ending involves the policeman removing the ribbon from the girls neck and her head rolls away. It was a great adaptation and a very scary episode.
