I very vaguely remember part of a TV show around 1980-1982. In it a lady had some medical treatment, then went on the beach. She promptly grew a huge amount of hair all over her body so she looked like a Yeti-type creature. Then she attacked a man on the beach. I was terrified. I think it was a TV show because there was a logo at the beginning and end of the adverts. It was an animal face I believe. Please help me find what it is.
