Lambs of God is a dark, gothic tale about three nuns, each a generation apart, living in an isolated convent by the coast, and an unwelcome visitor who enters their lives and changes their world forever.

The nuns, who live in solitude from the rest of the world on a remote and rugged island, have their lives turned upside down when an ambitious young priest, Father Ignatius, accidentally stumbles across the three Sisters as he arrives on a mission from the Church.
