Twins, Eden and Sierra, may be identical in looks, but not in temperament. While the domesticated Eden is happy to be a homemaker, Sierra hates cooking and cleaning and is not at all happy with her parents' suggestion that it is high time she got married - especially when they propose a match with the goat herder's son! Eden is more amenable to the idea of marriage, for she has fallen in love with the handsome Brett Sutherby, the new town preacher - and it appears the attraction is mutual. But when Sierra finds out that her sister had previously been writing to Montana rancher Beau Rivers and had agreed to marry him, she is rather taken with his photograph, and an idea begins to take shape...

Beau is delighted when his mail order bride turns up, for she is even prettier than he ever imagined. He initially turns a blind eye to the fact that she's a lousy cook and keeps the place like a pigsty, but takes her over his knee for a spanking when she continues to sass him. And when the deception is eventually revealed, both sisters get their well-deserved comeuppance from husbands who love them but won't stand for any nonsense!
