A hand plugs a cord into a power strip on a wooden surface, then the scene cuts to a person in a white helmet with black eye and mouth cutouts standing on a stage, then the view shifts to a crowd dancing under green lights, then the person in the helmet is seen from behind a crowd, then the crowd is shown from behind with arms raised, then the person in the helmet is seen from the front, making a hand gesture, in front of a crowd and a banner with the letters M, A, and Omega.
