In 1956 France, a priest is violently murdered, and Sister Irene begins to investigate. She once again comes face-to-face with a powerful evil.

In a small town in central France, Simon is a priest devoted to his parish. During a mass, Louise, whom he hadn’t seen since his seminary years ago, reappears. She introduces him to Aloé, an 11-year-old child, who is his son. This news will disrupt his daily life: can he be a good priest for his parishioners and a good father for his child? Simon will try to convince the highest authorities of the Church that his vocation is compatible with paternal love.

Set against the backdrop of a summer on the French riviera, the Roussier family and its fragile equilibrium is shaped by the uncertain diagnosis of 13-year-old Bertille, who suffers from a severe disability. Her parents and older sister Marion live in constant fear of losing her. Disconnected from typical teenage dreams, Marion seeks escape in a relationship with an older boy. When a new diagnosis emerges, the family’s future is redefined, opening up unexpected possibilities. Bertille will live, and so will her family.
