After several arson raids in the forest, Vincenzo and Pietro investigate the culprit together. The owner of the ski resort hired an arsonist to expand his pistes on the site of the burned-out forest. Vincenzo wrongly suspects Simone, who has a criminal record, but the boy's innocence is proven. Roberto, the son of the owner of the Flores factory, is also responsible for the fires and is accused of murder: he killed his father and set fire to the factory. His motive was that his father did not want to agree to sell the family factory to a French multinational, and he was sickly jealous of his adopted brother Simone. By coincidence, Silvia and Vincenzo enter the dance competition together, and at the end of the evening they kiss each other.
