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, a long drought means the cattle are running out of grass, and her dad has told her she can't adopt another mustang.

Even worse, the mare is skittish and unruly after being hurt by her former owners. Can Sam get the frightened horse to trust her and find a way to give her a home?
