The duke's finances are on the verge of collapse, and Lance, who was unaware of the renovation project his brother had commissioned, wants to terminate the contract, but knowing Catherine's passion, he allows her to stay in the hope that she will add value to the castle when it is eventually sold. The two are attracted to each other from the moment they meet, but Lance, unaware of Catherine's origins, reluctantly considers marrying the dowager daughter. Then, by chance, he learns that Catherine is the daughter of a wealthy man, and he proposes marriage to her as if it were destiny. But the duchess is not allowed to take up her profession...
