Afraid of marriage, Simone (Mary Ellis) breaks off her long term engagement with her fiancé Paul de Lille (Tullio Carminati). Paul heads to the top of The Eiffel Tower with thoughts of suicide. In another part of Paris and also afraid of marriage, Mignon (Ida Lupino) breaks it off from her young lover (James Blakely). Despairing, Mignon also climbs to the top of the The Eiffel Tower intending to leap to her death. There she meets Paul and the two compare stories. After discussion, Paul dissuades her from leaping and the two conspire to make their respective partners jealous by pretending to have an affair with each other.
