A group of people protest in an urban area, likely in Europe given the architectural style of the buildings in the background. They hold Iranian flags (with lion emblem), signs with images of people and text, and use mobile phones, possibly to record the event. The protesters are dressed in dark clothing, some wearing sunglasses. They are shouting in unison, expressing a message, presumably about political or social issues related to Iran. The environment is outdoors on a cloudy day.
