Modern noir thriller that has the legendary Orson Welles travelling to Rome and becoming embroiled in a murder mystery. In 1948, having just divorced the screen icon Rita Hayworth, director Welles (Danny Huston) escapes Hollywood by flying to Rome for an acting role. Trying to raise money for his next project, Welles' attention is diverted when one of his cast is murdered on-set, leading him into a new role as an amateur sleuth. Helped at every turn by his trusted driver Tommaso (Diego Luna), an ex-policeman, Welles is soon hot on the trail of the assassins. But when a list of potential targets appears, with Welles' name writ large, a political conspiracy involving all levels of the establishment seems to be on the cards.
