It's the Lake District, 1908. To all appearances, Livia, Ella and Maggie Angel lead a privileged life in a large country estate, with seemingly little to disturb their happiness, but since the death of their mother, their family home has been a far from a quiet haven for them. Their bully of a father, Josiah Angel, who runs a high-class department store and has aspirations of becoming the town mayor, sees his daughters as mere bargaining tools in his property empire. . . When the sisters discover their father had an affair many years ago, which resulted in the birth of a baby girl, they determine to find their half-sister, and their search begins in the local workhouse. Mercy, however, is not so sure she wants to be found - throughout the hardships of life in the Angel family, the four sisters must learn to pull together to survive, and to choose their own destiny.
