Sara, Ester, and Miriam are three sisters who have never left the farmhouse where their father and grandmother raised them. They are a Christian family, and fully respect the Old Testament dogmas, believing in no intermediary, no Church, and no sacred image. Grandma Paolina rises to all those roles that separate the girls from the Lord’s grace. However, the sisters are becoming women, and when their young cousin Primo is forced to come to the farmhouse, their lives are forever changed.
