Spanning the years 1900 to 1977, 'The Covenant of Water' follows a family in southern India that suffers a peculiar affliction: in every generation, at least one person dies by drowning - and in Kerala, water is everywhere. At the turn of the century a twelve-year-old girl, grieving the death of her father, is sent by boat to her wedding, where she will meet her forty-year-old husband for the first time. From this poignant beginning, the young girl and future matriarch - known as Big Ammachi - will witness unthinkable changes at home and at large over the span of her extraordinary life, full of the joys and trials of love and the struggles of hardship.
