Sir Robert Rannaldini, the most successful but detested conductor in the world, had two ambitions: to seduce his ravishing 19-year-old stepdaughter, Tabitha Campbell-Black, and to put his mark on musical history by making the definitive film of Verdi's darkest opera, Don Carlos.

As Rannaldini, Tristan, his charismatic French director, a volatile cast and bolshy French crew gather at Rannaldini's haunted abbey for filming, it is inevitable that violent feuds, abandoned bonking, temperamental screaming and devious plotting will ensue. But although everyone wished Rannaldini dead, no one actually thought the Maestro would be murdered. Or that after the dreadful deed some very bizarre things would continue to occur.
