A young girl, Isabelle, who follows his results with admiration, declares her love for him and becomes engaged. The reactions of his former colleagues bring Pierre before the courts. A misunderstanding with Isabelle thwarts the wedding plans. Later, the young girl, suffering from a brain tumor, allows herself to be cured by the healer.
