During the First World War, a British officer - David Compton - on leave from the trenches in Paris falls in love with and has a liaison of three days with a French performing artist: Deloryse/Lola. He proposes to her and tells her to get ready for the wedding in an hour. He rushes to search for the English church. On the way he meets his superior, who tells him that he has to report immediately, they have to leave Paris. He doesn't even have the time to see his fiancé again. After returning to fight on the front, he suffers from shellshock and forgets everything that happened in the last four years. After recovering he goes back to his wealthy life of rich industrialist, marries a British Socialite, with whom he runs entirely separate lives. She is the one to invite Deloryse to London to dance on one of her charity events. While dancing and singing on the stage she sees him in a loge. During her second number, where she sings the same song of when he met her in Paris, he finally has a flash back of the song and the singer. After the performance he sends her a notice that he wants to see her. She's very excited, but when Doctor Gavron comes to see her, he measures her pulse and tells her, that she has to give up the stage, as the strain might kill her, even if she dances once more. Then David comes. He meets her and his son Davey. But  he is now married to a British Socialite: Vesta Compton, who never wanted children, to the big regret of her husband.
