Later, Laura at the police station finally manages to identify Tonnara by giving a face to Scalise's persecutor. Meanwhile, in the precinct, Luca, following some investigations connected to a dog found at the end of its life, has discovered that a dog breeder is actually a crook who organizes clandestine fights, sending several animals to the slaughterhouse.
