The work of Savior Saint-Yves, a clinical psychologist, and his personal life still go side by side: old familiar patients return - Ella-Elliot, Margot, Blandina, Frederica, new ones come for consultations - the fragile girl Sarah, who hears voices, Muriel Robertson, a survivor of childhood trauma, ten-year-old Geraldine with an eating disorder, and the Savior is ready to help everyone and understand themselves. The grown-up children of the Savior and Louise - Lazarus, Paul and Alice Rocheteau, Gabin - give them surprises, from which there is not a moment of peace in the family. All events take place on the eve of Christmas, and unexpected and long-awaited changes are coming to the Saint-Yves family.
