At thirty, Laurence has everything she needs to be happy: a fascinating job, a loving husband… But one vital thing is missing: a child. Fragile following a miscarriage, Laurence meets a faith healer, Edith. Edith, a former nurse in her fifties, has developed a highly personal method of treatment based on breathing and energy. Thanks to her, Laurence's health improves greatly. A passionate relationship forms between the two women. Soon, Edith, the warm-hearted friend, invades the young couple's private life. Even worse, she represents an insidious, increasingly stifling threat. When Laurence gets pregnant, she doesn't tell Edith. Hounded by her murky past, Edith has to leave. Four years later, Blanche is born. Laurence seems happy and serene. The doorbell rings. Edith is back. She has come to collect payment for her debt. Torn between fear and guilt, Laurence has to face all her inner demons through Edith.
