Peter Standish Tyrone Power is an American atomic scientist who is working in a nuclear laboratory in London. His coworker Roger Forsyth Michael Rennie, who is worried about Peters lack of social activities, takes him to a house in Berkeley Square he inherited. It is there where Peter announces his wishes of living in the 18th century among the highclass family Petigrew he has studied the last years. Because of a lightning strike, he is brought back to 1784, where he is thought to be the first Peter Standish, the American cousin of the Petigrews who, according to history, will soon romance and marry Kate Petigrew Beatrice Campbell. Peter falls for Kate, but he is more interested in her sister Helen Ann Blyth, of whom he has never found any records. Over the next few days, Peter makes several bad impressions on the family by using modern day language and revealing information he could not have known if he had actually grown up in the 18th century. Helen, however, is the only one not suspicious of Peters presence and falls in love with him as well. Peter admits to her that the 18th century is not what he thought it would be. The narrowminded people, the poverty and the dirt irritate him. Furthermore, he admits that he is from the future and shows Helen his hidden laboratory in the basement with modern inventions. Rather than being afraid, Helen becomes even more interested in Peter. They fall in love, despite Peters awareness that he has to marry Kate in order to not change history. Helen begs him not to say things which makes him look odd, and that night, at a formal party, Peter tries to impress the famous Duchess of Devonshire Kathleen Byron, but he accidentally talks about her as if he is talking about her legacy, which makes her uneasy. Kate is fed up with Peter and announces that she will not marry him. Rather than trying to court her somehow, Peter is drawn to Helen, who is interested on finding out more about the future. Things start to look bad for Peter when his laboratory is uncovered. He is committed to the Bethlem Royal Hospital. Before being brought away, he rushes to Helens room, where she places a crux ansata to remind him of her love for him. While being taken away, lighting strikes again and Peter is back in present life. There, Forsyth tells him he has been acting like a mad man for the past seven weeks. Peter is shocked when he meets Forsyths sister Martha also Ann Blyth, who resembles Helen. He rushes out to the graveyard in front of his house, where he not only discovers Helens grave, but that she died of grief shortly after he was taken away to the asylum.
