Paris, 1950. Jürgen is sent to Paris as a reporter to cover the preliminary negotiations for the establishment of the European Coal and Steel Community, where he unexpectedly meets Marie again. During the war, Jürgen, a Wehrmacht officer, was stationed in Marie's village. At that time, the two were involved in a passionate love affair that they had to keep strictly secret. Now Marie wants nothing more to do with Jürgen. Because she is hiding a secret. Not even her best friends know that Pierre is Jürgen's son. Everyone believes that Marie was raped during the war. Only her parents and brother had noticed Marie's love for a German at the time, disowned her from the family, and chased her out of the village.
