Young, reckless and provocative Princess Claude makes a surprise visit home, torturing her already haunted mother, Catherine. Francis is pressured by Narcisse to act against his conscience or risk his throne and his wife. Mary finds a new ally in Condé. Francis confides in Bash and hatches a plot that involves an uncertain Lola. Kenna mistakes Claude for a newfound friend, while Greer returns earlier than expected from her wedding tour.

With a holiday celebration around the corner, Bash uncovers what could be the answer to Francis finally escaping the oppressive thumb of Lord Narcisse, and the two formulate a daring plan. Meanwhile, Mary proposes the radical idea of marrying the Protestant Lord Condé (Sean Teale) to the Catholic Claude, a scheme that she believes a viable path forward to peace, but Claude has other plans in store. As preparations are made for the upcoming feast, Greer discovers that she may be more involved with the Protestant movement than she originally thought.
