When war is declared in 1939, Andrew and Victoria Pringle are expecting their second child. What should be a happy time is marred by the threat to the peace and future of their beloved glens. As their family grows up, they take comfort in watching them thrive, delighted that young Libby, the only girl, inherits their love of the land. Libby and the laird's illegitimate grandson, Billy, become great friends.
But when tragedy strikes, Billy blames himself. He moves to Yorkshire to start a new life, but is forced to ask himself whether he is able to stay away from the glens and from the friends of his childhood.
