A vigorous story of America's last frontier.

The foreman of a ranch owned by a pretty young girl captures a herd of wild horses, but the herd's lead horse manages to break them free. The foreman blames a drifting cowboy, Yak, for the break-out. Yak, however, seems intent on provoking a confrontation with the foreman at every opportunity--and, as it turns out, for good reason.
