Back to the Future (1991)

Season 1: Episode 2

Doc causes another power cut in his lab whilst trying to invent something. Jules and Verne are annoyed because their toy car racing has been interrupted (it runs on electricity) and Clara is annoyed at the lack of power as well. Feeling that his family has become too dependant on technology since they moved to the 20th Century, Doc uses the DeLorean to take his family back to Medieval England. The family are not happy, especially when Doc sends the DeLorean several hours into the future so there is no way they can go home until then. Clara walks off and after meeting some Medeival women washing in the river she meets Lord Biffingham of Tannenshire. Biffingham takes a shine to Clara and when she turns him down he kidnaps her. Doc tries to save her but eneds up being kidnapped as well. Biffingham imprisons Clara in his tower and decides to marry her - once she has become a widow! And he plans her to be a widow very shortly by challenging Doc to a joustling match.
