What does an honest cop do when his bosses are on the side of the lawbreakers? Outwitting prosecutors, politicians, mobsters and run-of-the-mill kidnappers and killers, Detective Aurelio Zen (Rufus Sewell) brings justice to modern-day Italy, whether the authorities want it or not. The episodes are based on the bestselling novels by Michael Dibdin. Vendetta: A killer is on a vendetta-fuelled rampage against those who wrongly imprisoned him, including a cop who had almost nothing to do with it: Aurelio Zen. Can Zen juggle staying alive, investigating a politically-charged murder and courting his new officemate, Tania, at the same time?
