In 1667 in France, Louis XIV is a young king who wants to impose his power whereas he is traumatized by the Fronde (the revolt of nobility during Louis XIII's reign) and despite the attacks of conspirators. Then, Louis XIV decides to establish the seat of the power out of Paris, in Versailles. At that time, Versailles is just a hunting lodge but Louis XIV radically wants to transform this castle.

The Queen gave birth to the first royal baby and it triggers some rumors. Besides, Louis XIV's counselors advice him to go to war in order to impose his power. Furthermore, Louis XIV's brother Philippe dreams of glory and want to be on the field of the future battles.

Louis has one thing in mind: Versailles. For the nobles to come to Versailles, the king demanded the representatives of high society bring him their noble titles, only guarantors of their privileges. First to be stripped of his title, Montcourt seeking the support of the Duke of Cassel, one of the North's most powerful nobles, who bears the king in high esteem. Louis asks the queen to leave the mourning to welcome his guest: Prince of Assini, able to open his trade routes in West Africa.

Louis was furious on hearing the exploits of his brother Philip on the battlefield; some see it as the most valiant fighters of the army of His Majesty. Louis is furious to learn that the Parthenay family was assassinated on the road to Versailles, a powerful family of South nobles, who came to assure him of their support. If the roads leading to Versailles are not safe, no noble will venturer it. If Versailles is isolated, then the king should give up his plan. Inconceivable for the monarch who sends Fabien Marchal, the head of security, conduct the investigation into the murder of Parthenay and bring the head of the murderers.

Hero of the battlefield, Philippe returns from the front transformed. The French soldiers admire the Duke of Orleans, all wreathed in glory. This recognition begins to overshadow Louis. The roads are still not safe just outside Versailles and convoys of attacks are increasing. To celebrate the peace treaty he just signed with the Spanish, the King decides to invite the biggest noble families in Versailles for great entertainment. He invites the Duke of Cassel.

After the war, the soldiers were requisitioned to carry out the work on the palace of Versailles. But worn by the hardness of their task, their lives and broken promises, they revolt. Two thousand of them lay down their tools. Convinced by Madame de Montespan, the Duke of Cassel went to Versailles to attend the festivities. The king has just decreed that nobles that locate in the area will be relieved of their debts. No castle or land, the Duke of Cassel must resolve to stay.

With Louis laid low by a major fever, those conspiring against him grow in strength and confidence while Philippe is caught in the middle, as are medic Masson and his daughter Claudine.

While Louis proposes an audacious alliance with England, and an unexpected envoy to negotiate it, normally brazen Béatrice fears revelation of her secrets. The `palace of dreams' is home to murderous schemes as the extravagant drama continues.

The traitor strikes in the palace prison, Henriette has a rocky reunion with her brother, Charles II of England, while Béatrice risks a rendezvous with Marchal. Diplomacy and duplicity dominate the drama's penultimate episode.

The traitor changes tactics, striking at those closest to Louis, with deadly consequences while Sophie stubbornly risks angering Marchal. A brutally bloody finale to the first season of the bold historical drama.
