two people standing in the back of a maroon pick-up truck. A woman is speaking into a microphone and gesturing. A man stands next to her, looking at his phone. There are several black, horn-shaped loudspeakers mounted on a metal frame above them. A red generator is visible near the woman. A sign in the back of the truck reads "Freedom for Political Detainees." Other people are visible in the background, along with buildings and trees. The scene appears to be a protest or rally on a city street.
