4x12 - Distretto di Polizia

The District agents work on the case of the discovery of a body on the banks of the Tiber and discover that the victim, a photographer responsible for an environmental association, was investigating the deliberate pollution of the river. In the meantime, five people who escaped the fire of a local supermarket arrive at the police station and are looking for the hero who saved them by opening an escape route for them. And who knows, maybe it's someone who works at the Decimo Tuscolano. Giulia, in the meantime, continues her research on her father's case and manages to check the contents of some CD-ROMs found in Greco's house.
