As a young married couple living in Australia's rugged high country, Andrew and Anne work together to make the very best of their property. In time it will pass to their son, David, who is determined to become the best sheepdog handler in the country. Nothing is going to stand in his way - not even the beautiful daughter of the wealthy graziers next door.
The Half Moon Valley is not easy to farm, nor are its inhabitants easy to know. But the valley produces the best superfine merino wool in the country, and Dan Stafford is its top woolgrower. Dan relies on his capable son, Jim, and his two eye-catching daughters, Bella and Beth, to help run the property. Now he is battling to retain its prize-winning status. When Bella marries and moves away, and the neighbouring property is sold to an outsider, Dan is unnerved. At least Beth seems content to remain on the land. But Dan's new woolclasser, the intriguing Rod Cameron, turns out to be more than Dan bargained for. With Rod on the scene, Dan's status and Beth's future are far from assured.
