Carlo Gesualdo – beastly murderer and divine composer – is one of the most striking figures in the history of music. Based on his dramatic honor killing, the film tells the story of multi-facetted, revolutionary music and the search for forgiveness. Through the power of music, the film explores the thin line between fascination and disgust. How is it possible to commit a capital crime, yet write divine music? Are crime and genius interwoven? And can salvation through music be achieved?
