The Atlantic's first feature documentary is the definitive inside story of the movement that has come to be known as the alt-right. With unprecedented access, White Noise tracks the rise of far-right nationalism by focusing on the lives of three of its main proponents: Mike Cernovich, a conspiracy theorist and sex blogger turned media entrepreneur; Lauren Southern, an anti-feminist, anti-immigration YouTube star; and Richard Spencer, a white-power ideologue. Directed and shot by Daniel Lombroso in his directorial debut, this film takes the viewer into the terrifying heart of the movement -- explosive protests, riotous parties, and the rooms where populist and racist ideologies are refined, weaponized, and injected into the mainstream. Just as the alt-right comes to prominence, infighting tears the movement apart. Spencer and Cernovich clash over the role of white nationalism in conservative politics. Southern struggles to reconcile her leadership role with the sexism and misogyny of her peers. Lawsuits mount and internecine fights erupt, but even as the alt-right fractures, its once-marginalized ideas find a foothold in mainstream discourse; in Republican politics; in the establishment right-wing press, especially Fox News -- and on the world's biggest social-media platforms. As white-nationalist violence surges in America and across the world, White Noise represents an urgent warning about the power of extremism, and where it's going next.
