A man in crisis / The bad teacher

Bianchi's body is found, killed by Sabatini and thrown into the river, but there's no trace of the tablet recording the drug trafficking. Claudio, promoted to head of the unit by Zaccardo, plots to have Ardenzi expelled from the station, now at war with his former friend. Ardenzi, with the help of his team, decides to search for the gun used to kill Bradic, which Sabatini may still be hiding in the house. Roberto finally manages to confess to his daughter about her mother's true death, and their relationship grows stronger.
