The film, a smart political thriller, focuses on the four bodyguards protecting an honest, imperiled judge brought in from Rome to clean up a Sicilian town (Trapani). The previous judge and his escort had been assassinated when they came too close to blowing the whistle on a local water scam. The new investigator, Judge De Francesco, takes up right where his predecessor left off, shutting down the city’s water and creating an unpopular artificial drought. Corrupt local politicians, working hand-in-hand with the Mafia, will stop at nothing to prevent exposure of their rackets.The story is based loosely on the life of an actual judge, Francesco Taurisano.
