1435. Rouen. Jacquetta of Luxembourg is left a wealthy young widow when her husband, the Duke of Bedford, dies. Her only friend in the great household is Richard Woodville, the Duke's squire, and it is not long before the two become lovers and marry in secret.

The Woodvilles return to the Lancaster court, where Jacquetta becomes close friends with young King Henry VI's new queen. But she can sense a growing threat from the people of England, and the danger of royal rivals.

Jacquetta fights for her king, her queen and her daughter Elizabeth Woodville, for whom she senses an extraordinary future.
