The county of Singletree, Montana has a problem with rustlers. Cyrus McCall strings barbed wire between his land and that of his neighbour, Maggie Carter. But this means that Maggie must herd her cows an extra two miles to their drinking water, taking time and manpower she can't spare - not to mention implying she is in league with the rustlers who push stolen stock across her land. Maggie promises hell if the fences aren't taken down - and hell is what she and McCall will get.
