Plot summary

Kang Min-woo leads a quiet life in Gwangju with his younger brother Jin-woo, a student. In May 1980, martial law troops enter the city, accusing residents of plotting a communist revolution. Soldiers attack students and other civilians in the streets, and tear gas and beatings reach a movie theater where people had gathered. As the violence spreads, citizens who have watched neighbors and family members hurt begin to organize, forming a militia to guard their homes and each other. The retired officer Park Heung-soo becomes a leading figure among them. Min-woo tries to keep Jin-woo, who is angry at the treatment of his classmates, out of the protests, even as he is pulled into the citizens' defense himself.
