Four decades after taking to the stage for the first time, Fermín Muguruza launches into his last major tour: a collective journey to celebrate 40 years of music, engagement and cultural resistance. This music documentary captures the pulse of that voyage: concerts packed to the hilt, endless kilometres on the road, all sorts of encounters on the way and a shared energy that stretches beyond generations, from the bands Kortatu and Negu Gorriak to his current solo career.​
