Larry Towell is a photographer with the prestigious Magnum agency. For 40 years, he has travelled our troubled planet, capturing the unspeakable. In this cinematic diary, he looks back on his profession, his doubts, the need for images, the absurdity of borders, the danger of “getting used to war” and the essence of his quest, which is also that of the film: humanity. Yet another impressive work by Matthieu Rytz, talented filmmaker born in Nyon!
