Politician Mario Chiesa’s arrest ignites a nationwide scandal: Italy’s Tangentopoli. As the political fallout spreads across the country, we follow the intertwining lives and ambitions of six main characters.

Police officer Luca finally gets his man, Leo's murky past is threatened to be exposed and Gulf War veteran-turned-politician Pietro grows disillusioned with parliament.

A suicide shakes the consciences of many of Milan's power players and forces everyone to confront their responsibilities and their political ambitions.

Luca is forced to face his darkest demons, Leo reflects on a morbid episode from his past and Pietro and Veronica find their lives heading in totally opposite directions.

Luca holds a secret meeting with Bibi, Leo takes a risky decision in order to brighten his future and Peter finds a reason to fight in parliament.

Luca breaks a few rules in order to pursue his investigation, Leo believes he has finally shaken off the demons from his past and Pietro turns his attention to war veterans.

While ongoing investigations destroy the lives of more politicians, Pietro discovers that there is a mole hiding in the clean hands team.

The investigation is one step away from unearthing the deep-rooted corruption within the Italian political system. Meanwhile, ghosts from Leo's past come back to haunt him.

The Italian drama draws to a close and the vast network of political corruption is set to be exposed. But whose fate will be sealed and who will live to fight another day.
