Zen is a British television mini series produced by Left Bank Pictures for the BBC, co-produced with WGBH Boston for its Masterpiece anthology series, Mediaset and ZDF. It stars Rufus Sewell and Caterina Murino and is based on the Aurelio Zen detective novels by Michael Dibdin. The series was filmed on location in Italy, but the dialogue is in English. The series, which comprises three 90-minute films, was broadcast in the United Kingdom on Sunday evenings from 2 January 2011 on BBC One. The three films were based on the books Vendetta, Cabal and Ratking.
Detective Zen is sent to a remote village to re-investigate a murder, which may spark a political scandal. Zen is under pressure from the politicians and the Chief of Police, but he would rather be spending time with Tania, the Chief's beautiful assistant. Meanwhile, a gangster is after Zen, seeking revenge.
The death of a famous aristocrat, Umberto Ruspanti, leads Detective Zen into the shadowy world of The Cabal - an organisation more powerful and secret than the Mafia. The Ministry want a quick verdict of suicide, but Zen's not so sure. Meanwhile, things are looking up with Tania.
After industrialist and political party funder Ruggerio Miletti is kidnapped, the Ministry turn to Aurelio Zen, to get him back alive at any cost.
