Mary's ship washes up on Scotland's shores. She watches as soldiers kill those who are alive and when she tries to cry out, Narcisse quiets her. Just as the men are about to kill Bash, a group of Druids arrives on the beach and takes him away. Mary and Narcisse follow in hopes of rescuing him.

Elizabeth prepares to entertain the Prince of Denmark and asks Lola to flirt with his companion. He turns out to be the more attractive of the pair, which stuns Elizabeth and Lola. Claude confronts Catherine about having her beaten on her wedding night and Catherine tells both of her children to keep their disdain at bay until they can capture or kill the Red Knights.

Charles plans to bring down the Red Knights on his own so the privy council will declare him of age. In doing so, he will become the leader and he will abolish the regency. 

Mary and Narcisse follow the Druids. He believes they are evil people who will kill them the first chance they get. He suggests they pretend to be siblings in order to find Bash. Elizabeth talks with the Prince of Denmark who is quite full of himself and his country. While he prattles on about Denmark, she grows increasingly irritated. Lola's companion is quite charmed by her.

Narcisse and Mary enter a tent where a medicine man is performing a ritual to save Bash from Sea Breathe. Mary and Narcisse believe he will be harmed, but the ritual works and Bash's health is restored.

Charles and his "Phantom Brigade," a group of teenagers, begin trying to find information about the Red Knights. One of them has a tip which might be what Charles needs.

Elizabeth continues entertaining her guests, but she has a difficult time allowing the men to win. Charles reveals his new information to Claude and Claude tells him she plans to marry a member of the Kingsguard when Charles asks for protection on his trek to Orsay. Claude brokers a deal which will make Leith a Duke.

Mary and Narcisse learn more about the Druids and their enemies. They are hunted by a group of men called the Wulvers, half-men, half-wolves, and those were the men Mary saw on the beach. Senneck tells them Scotland is a land fractured by hate in need of a unifier.

Charles and Leith find a stockpile of weapons in a silo in Orsay and make a plan to return and blow it up. Lola's suitor propositions her to join him in his chambers that night while Prince Magnus asks Elizabeth to credit Denmark with saving her people from famine. She refuses and storms away from the table. He later bans Lola from Denmark. For life.

Mary finds Narcisse packing his bags with plans to leave in the night. She asks him to stay by her side until she gets to Edinburgh and regains her throne. He refuses and sets off on his journey to rescue Lola.

Claude and Leith make a plan to travel to Orsay. When Leith suggests Charles stay behind, he refuses and holds marriage to Claude over his loyal guard.

Elizabeth visits Lola and questions why Lola might have been so quick to take the blame for England's declaration of war on Denmark. She suspects Lola has been trying to gain her trust so that she might share information with Mary. Lola manages to talk her way out of it. This time.

When Mary sets out to leave the Druids, Senneck reveals that he knew who she was when he looked in her eyes. He gives her advice and a blessing and then they are attacked by the Wulvers. In order to hide from the clan, they hide inside the Wicker man in hopes that when they are found, the Wulvers will take pity on them.

Elizabeth visits Lola once more and tells her of a boat of mercenaries who crashed off Scotland's shore. They believe Mary is dead and Elizabeth turns the moment of treachery into an invitation for Lola and John to stay in England as English subjects. 

Charles, Leith, and Charles' friends make their attack on Orsay but the silo doesn't erupt. Felix rushes in to see what's happening and Leith has to go in and rescue him. As the villagers fight the Kingsguard, Leith is injured and Charles begins walking back to the castle when he's kidnapped by one the Red Knights. One of his loyal friends is a traitor.

Bash kneels to help one of the Druids who survived the attack. While preparing for the next leg of their journey, Mary spies a pin on the cloak of one of their new traveling companions and recognizes it as the seal of the clan who ordered her assassination and ended up killing Francis instead.
