La Serena rises above the waters, protected by the demons that inhabit them and during carnival time, they come out of the canals and attend the festivities in her honor. In between dances, a conspiracy is born. The Duchess plans to sabotage the pact with the demons to reopen the borders; the artists plot a rebellion; the young Mirlo discovers the secrets of the demons and an influential aristocrat, Baldizere, plans a coup d'état. The Malatesta twins have accepted an unusual assignment: the theft of a treasure, without knowing who their client is and the fundamental role they will play in the fate of the city.
