German troops are fast approaching Paris. Georg, a German refugee, escapes to Marseille in the nick of time. In his luggage, he carries the documents of an author, Weidel, who has taken his own life in fear of his persecutors. Those documents include a manuscript, letters and visa assurance from the Mexican embassy. Everything changes when Georg falls in love with the mysterious Marie. Is it devotion or calculation that has led her to share her life with a doctor, Richard, before journeying on in search of her husband? He's said to have surfaced in Marseille in possession of a Mexican visa for him and his wife.
