When Sam rescues an abused mare from a group of outlaw horse rustlers, she knows she's done the right thing. But the ranch already has a full corral, and a long drought means the cattle are running out of grass. And her dad has told her she can't adopt another mustang. If that weren't enough, the mare is skittish and unruly after being hurt by the rustlers. Can Sam get the frightened mare to trust her?
