Romantic dance

A crowd of civilians confronts a line of police officers in helmets and gas masks, pushing forward and grabbing at the officers' equipment in a tense, confined space. The scene shifts to a large, dimly lit room where a band in white uniforms and sombreros plays music for a crowd of people in dark clothing and helmets, who are gathered in a circle. The final scene shows a group of people in a narrow, dark corridor, some wearing helmets, moving forward in a tight formation.
