Four men plan a technically perfect crime, but the human element intervenes... (imdb)

Based on the real life of German spy Anne Marie Lesser during World War I.

Serenade represented the return to the screen of international favorite Lillian Harvey after an absence of two years. Based loosely on the life of composer Franz Schubert, the film casts Bernard Lancret as Schubert, Harvey as his dancer sweetheart, and Louis Jouvet as a possessive Baron who has his own designs on our heroine. Ultimately, the Baron gracefully bows out of the girl's life, allowing her to serve as the inspiration for Schubert's classic compositions "Serenade" and "Rosalinde".

Somewhere in Tunisia, commandos of the First French Army are training, in preparation for the August 1945 landings on the southern coast of France. Lt. Claude Legrand (Georges Marchal), who leads the commando, finds among his men a former resistance fighter, Serge Duhamel (André Valmy), who feels nothing but contempt for the lieutenant. Some years earlier, Lt. Legrand and Duhamel had quarreled over Legrand's wife Simone, who had an affair with Duhamel.
