In 1786, Jocelyn entered the Seminary. He leaves his share of the inheritance to his younger sister Julie. In 1793, on the point of being ordained a priest, the Revolution forced him to take refuge in the Alps. There he meets Laurence, first disguised as a young boy. A great friendship binds them which turns into love when Jocelyn discovers the girl's true identity. Yet faithful to the promise he made to the Superior of his Seminary, Jocelyn will not abandon his faith.
