Flash forward to the postwar years, and the two meet again, sparking a passionate affair that spans two decades. But when Filomena — who has now become Domenico's kept woman and has secretly borne his children — learns that her lover is planning to wed another, she will stop at nothing to hook him into marrying her instead.
