A group of people march down a city street, carrying red flags and a white banner with black text. The banner reads "PLANTEM CARA A LA GUERRA I EL FEIXISME, CONSTRUIM L'ALTERNATIVA REVOLUCIONARIA". The people are mostly dressed casually. Trees line the street, and buildings are visible on either side. The sky is partly cloudy. The video is taken from a low angle, looking up at the marchers and buildings.
