I am trying to find out the name of a sci fi program I used to watch. When I watched it was on BBC Two on a Friday night after 10pmish and was aired about 1997 onwards. It was about a young woman, who had long blonde hair and she shifted in time and kept meeting a mystery man, she was called Sidney. I think she was a scientist. It was on at the same time La Femme Nikita was on on Channel 5 in UK. Thanks in advance.
