Plot
On his way to begin rehearsals at the Théâtre Montmartre, where he has secured the male lead role for an upcoming production, young Bernard Granger finds himself repeatedly rebuffed by a woman he attempts to flirt with on the street. Upon arriving at the theater, he discovers that the woman is actually the production designer, Arlette, who happens to be a lesbian. Bernard is then introduced to Marion, the owner of the theatre and its leading lady. Marion's Jewish husband, Lucas, serves as the theater's director, believed to have fled Paris; however, he is clandestinely hiding in the theater's cellar. Marion secretly releases him each evening, providing meals and materials for future productions. Their evenings are spent in the empty theater, where they engage in passionate discussions about the current production and make plans for Lucas to escape the country. However, Marion soon becomes infatuated with the oblivious Bernard, whom Lucas only knows from a headshot and snippets of conversation overheard through a rigged heating vent.
Unbeknownst to anyone at the theater, Bernard is a member of the Resistance group responsible for delivering the bomb that killed a German admiral.
The opening night of the production sees a full house, but the following morning a scathing review in Je suis partout, an anti-semitic and collaborationist newspaper, condemns the show as being "Jewish." The reviewer, Daxiat, aims to oust Marion and take control of her theater. While the cast and crew celebrate their initial success at a nightclub, Daxiat falsely accuses Bernard of insulting Marion at another gathering. Bernard eventually finds Daxiat and severely beats him in the street. On another occasion, two Gestapo agents, disguised as air raid wardens, conduct a search of the theater, prompting Marion to turn to Bernard in desperation for help in concealing Lucas and his belongings.
Following the arrest of Bernard's Resistance contact during a Gestapo raid, Bernard resolves to devote his life to the Resistance cause and abandon acting. As he prepares to leave his dressing room for the last time, Marion enters to bid him farewell, and the two share a passionate encounter on the floor.
After the war ends, Bernard returns to the theater to star in a new play written by Lucas during his time in hiding. On opening night, Marion, who plays the female lead, expresses her desire to share her life with Bernard, but he confesses that he never truly loved her. As the curtain falls, Bernard, Marion, and Lucas stand hand-in-hand to receive the applause of the audience.
