Joe Roark's three daughters have just learned that the only way they will inherit their father's ranch is to drive a herd of 1,200 longhorns to Dodge City, Kansas and sell them there. If they fail, his wife Lola inherits everything. Terrified, but knowing they will be penniless without their inheritance, the girls decide to drive the cattle. What follows is an unparalleled adventure filled with the raw wildness of nature, the force of sheer determination, and an unexpected love that will change one sister's life.
