Randy and his family leave Texas in 1877, and after a three month trek reach Wyoming where they must literally tear an existence from the wild country. The mother and father, with their two sons, are well equipped to do this, for aside from their courage they have frontier know-how and the telling of their attempts to clear a homestead and capture a herd from a group of wild longhorns is beautifully achieved. However, every effort they make progresses only to the starting points, for they have an implacable enemy. Their section is dominated by grizzly bears. One that they dub ""Old Spook"" claws into their every dream. He had invaded their cabin when they were out, he had dragged off Randy's first -kill and he preys on the painfully won herd. Randy and his father know that they must hunt this grizzly down, but keep putting it off in favor of the building, herding and clearing they must do. When ""Old Spook"" attacks and almost kills Mr. Sam, Randy's spunky little brother, Randy and his father set off and in a hunting scene that portrays the dual hunt -- man against animal and vice-versa-- big the grizzly is brought down. As father and son plod home in exhausted triumph along a game trail, Randy sights in the distance -- another grizzly bear. Very well done.
