When an engineer is viciously killed, Teresa Battaglia, a commissioner from Udine, is called in to investigate the case, with the assistance of inspectors Giacomo Parisi and Massimo Marini.

The primary suspect in Teresa's probe turns out to be Mr Valent's wife; a mysterious person wearing black harasses kids at the elementary school in the mountain village; a skinned jackrabbit is found hanging in front of a little girl's house.

Marini finds Teresa in her car, uncounsious; the team investigate the discovery of the bones of a child who went missing years ago; the man in the cloak continues to harass Lucia's family; the killer attacks the mayor's son.

Dante Kravina, Lucia's father, is arrested; Lucas Ebran, a rude man from Traveni, becomes the primary suspect; the school janitor harasses Oliver, a friend of Lucia; a group of kids discover the bones of an unknown person inside a cabin in the woods.

The flayed body of janitor Abramo is discovered inside his car with his hands tied to the steering wheel; as the police are busy searching for Lucas Ebran during the festivities of St Nicola, Mathias's little brother gets abducted.

Mathias's friends take the police to the cabin they found in the woods; a disturbing discovery prompts Teresa and the team to deal with dark, old secrets.
