The Second World War has just ended for Russia when Mikhail finds a dying man and his German shepherd, Zasha, in the woods.

It's dangerous - some say traitorous - to own a German dog after the war, so Mikhail must keep Zasha a secret to keep her alive.

But how long can he get away with it? Mikhail's inspiring journey to save his best friend forces him to face some of life's hardest lessons about war, hate, forgiveness and hope.
