EL PAÍS and Cadena SER have launched a new documentary series titled 'The Ultra Wave', which examines the rise of radical far-right movements in Spain and beyond. The first episode, 'The Base', focuses on a specific neo-Nazi terrorist cell that posed a significant threat with a clear agenda of racial conflict aimed at destabilizing society. The documentary highlights the alarming trend of extremism in contemporary politics and society.

In 'The Base', viewers are taken through the details of Operation Cascadia, a significant police investigation that led to the dismantling of a dangerous supremacist group based in Castellón. This particular organization, known for its violent ideology and willingness to act, was actively preparing for imminent attacks. Through this gripping narrative, the documentary sheds light on the motivations and methods of such extremist cells while raising awareness of their potential impact on communities.

This series aims to inform the public about the ongoing threats posed by radical ideologies and the necessity for vigilance against their rise. By showcasing law enforcement efforts and the dangers of such militant groups, 'The Ultra Wave' seeks to provoke dialogue about the broader implications of extremism in society and the importance of counteracting it effectively.
