Sarah a young Carmelite nun, collapses in pain, dazed and spouting a nonsense phrase. Concurrently, a great distance away, her identical twin sister, Gaëlle, in prison, wakes up to find her cell in flames.

While Gaëlle, the victim of an attack by her fellow prisoners, is transferred to a different prison, Joachim, a Cecilian (both a doctor and a priest) visits with Sarah. He’s perplexed by her case because her tests all came back normal, and he deducts that her spells must have a psychological source. But Sarah isn’t forthcoming about her past, and Mother Emmanuelle, who runs the convent, doesn’t even want Joachim to treat the young woman.

Through his investigations, Joachim learns that Sarah has a twin sister, to whom she may have some kind of psychic connection. He discovers that Gaëlle went to prison for a horrible crime at around the same time Sarah entered the convent. Joachim is also dealing with the violence  of his own past. The Pact of Silence was based on a novel by Marcelle Bernstein. It was adapted for the screen by Roselyne Bosch (1492: Conquest of Paradise).
