Episodes on an Australian stockfarm, drawn with real understanding of horses and their psychology, their traditions; not straight story but episodic in treatment. Cascae is a new mare on the stockfarm, and her foal, Amathea, becomes the special darling of the manager. The round of her life is traced, -- branding, breaking, training as a stockhorse, winning of a race, and the pattern repeated in her own foul.
