Felice, a dark and beautiful Jewish woman who is constantly in danger of being apprehended by the Gestapo, works for a Nazi newspaper under a false name, feeding what she learns to underground resistance leaders. Lilly, a flowery blond housewife living in bourgeoise comfort, raises 4 little boys, passing the time until her Nazi husband, Gunther, returns from the war. When the two meet, and Felice makes advances, Lilly responds, falling into total submission under Felice's spell. They nickname each other Aimee (Lilly) and Jaguar (Felice), spending every night dancing to popular 40s jazz music with Felice's eccentric lesbian friends, and every day raising the four boys who treat Felice like a second mother. It is not until the end of their affair, when Lilly--and soon thereafter, the authorities--learns that Felice is a Jew, and tragedy befalls the couple.
