Fletcher Watkins is furious when his half-brother cuts off his allowance and names his newborn daughter as his heiress. With help from the ruthless gambler Jebediah Crabbe, he forms a callous plan to kidnap baby Blanche. Only a miracle saves the child and her gullible nursemaid Nesta from certain death.

Seventeen years later, Bronwen Jenkins has no idea that she is anything but the daughter of Nesta and her hard-working husband Jim Jenkins. So when Jebediah Crabbe and Fletcher Watkins appear in sleepy Cwmrhyddin Cross - intent on making a fortune by snaring Jim into an illegal bare-knuckle boxing match - Bronwen thinks only of saving her father from injury in the ring.

But if Crabbe and Watkins find out who she is, Bronwen will be in much worse danger herself . . .
