The British advocacy group Hope Not Hate fights the far right by investigating extremist groups’ methods and finances, often going undercover to expose their true agenda. Using hidden cameras and audio recordings, they document rallies, secret meetings, and online influencers who spread racial prejudice. Their work reveals how extremists seek to reshape mainstream politics and manipulate public opinion. The documentary Undercover: Exposing the Far Right follows activist “Chris” as he infiltrates a pseudoscience platform linked to a well-organized far-right movement spanning Europe, exposing its connections to political parties and efforts to influence key opinion-makers.
