Some kids in camp playing Soviet game zarnitsa ("capture-the-flag"-like). But with every minute kids become more cruel and heartless. After some time it comes to war crimes: torture, mutilation and looting.
The film tells the story of Zarnitsa - a mandatory experience for every Soviet pioneer. An entire summer camp is divided into warring parties of "blues" and "greens." If the paper epaulets symbolizing your team's color are ripped off, you are "killed."
