Film show: Syrian refugees haunted by horrors of war in 'Ghost Trail'

Inspired by a true story, "Ghost Trail" introduces us to the clandestine groups tracking down Syrian war criminals in Europe. Director Jonathan Millet joins us to talk about how he constructed an espionage film with amateur spies at its centre, and we discuss the long road to justice for the millions of Syrians devastated by the horrors of 13 years of war. Film critic Lisa Nesselson also takes us through Kevin Costner's passion project, "Horizon", as the first chapter of his four-part epic opens in French cinemas. Plus we get a rundown of the best road movies on show at the Cinémathèque Française.
