Three years have passed on Camellia Island. Sylvia and Maël are happy. Their daughter Luciane is now three years old, and soon their second child is expected to be born. Then, Maël's family past catches up with him: his mother, with whom he had no contact for almost 30 years, is seriously ill. Although Sylvia has a bad feeling about it, Maël leaves. In the following night, a devastating storm surge rages along the Breton coast. Camellia Island suffers severe damage, and Sylvia has a dangerous accident.
