Documentary exploring the campaign to save the US's last standing roller rinks from closure against a backdrop of growing racial tension. The film reveals the story of underground subculture that has grown up around these venues and given rise to some of the world's greatest musical talent - but has itself remained virtually unknown to the mainstream.

Patrik Hermansson went deep undercover, as Swedish student Erik Hellberg, at the heart of the alt-right. He infiltrated some of the most notorious far-right networks in the US and the UK, culminating in the violent clashes in Charlottesville. He extracted damning information that runs all of the way to the White House. And he caught it all on hidden camera.
