Cambridge 1912: A harmless bicycle accident disrupts the orderly world of young scientist Fred. He falls in love with an unknown young woman - and this cannot be explained by the laws of physics. Fred is a physicist, fully dedicated to science, and lives a bachelor’s life according to the statutes - until one stormy evening he becomes involved in a bicycle accident. He finds himself in a strange bed, next to a young woman: Daisy, a nurse from London's impoverished district. She is charming, pragmatic, and stunningly beautiful. For Fred, it is love at first sight! But as unexpectedly as Daisy entered his life, she disappears just as quickly. And while all of Cambridge passionately debates the emerging nuclear research and women's suffrage, Fred begins his search for Daisy.
