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. Cabal: A disgraced aristocrat jumps off a bridge. Or was he pushed? As usual, Zen gets mixed signals from his scheming bosses: the Ministry of Justice wants a ruling of suicide, while a powerful -- and beautiful -- prosecutor hints that Zen had better start looking for the murderer.
