Release Message:  An American atomic research chemist (Tyrone Power) changes places with his 18th century ancestor and falls in love with his fiancŽe's sister.

Description:  A scientist obsessed with the past transports himself back in time to 18th-century London, where he falls in love with a beautiful young woman. ///// Peter Standish (Tyrone Power) is living in an 18th-century house on Berkeley Square where his distant relative - also Peter Standish - once lived centuries before. But when he is struck by lightning, he suddenly finds himself in the 18th Century! Peter meets his ancestor's fiancŽe Kate Pettigrew (Beatrice Campbell) but it is her sister, Helen (Ann Blyth) with whom he falls in love. As Peter tries to hide his true, modern identity, a jealous Kate makes trouble and before long, Peter finds himself back in the present where his true love might not be lost after all. An American physicist, Peter Standish, lives in London in an inherited flat on Berkeley Square, unchanged from its 18th century appearance. He's researched his ancestors and the flat, and he believes somehow he will travel through time, if only briefly, to 1784. A lightning strike transports him, and he finds things disturbingly different than he expected: disease and social conditions appall him, and, in this Age of Reason, his speech, manners, and knowledge frighten rather than interest all except one young woman, Helen, the sister of the woman he's to marry. He sets up a laboratory in the hopes of hastening progress, and he tells her his secret. Does love or Bedlam await?
