BAFTA-winner Michael Winterbottom directs this psychological thriller, taking a fictionalised look at the real-life murder of a British student and the subsequent trial of her American housemate.
Film-maker Thomas (Daniel Brühl) is in Siena, Italy, to make a movie about the crime, with American journalist Simone (Kate Beckinsale) bringing him up to speed on the facts behind the salacious headlines. Seeking a guide into the drug-fuelled University nightlife, he enlists the help of British student Melanie (Cara Delevingne).
As Thomas becomes obsessed with uncovering the truth, the disturbing details of the crime scene cause him to question the motives of everyone around him, as well as his own. What dark secrets are held by the picturesque streets of this town where an innocent woman lost her life?
