A courageous teacher leads a group against a real estate developer who is determined to evict hundreds to make way for a construction project.

At a nearby newsstand, another man witnesses the arrest. He turns and walks away – with a limp. He is the gunman, and his name is Sergeant Sommai. After losing a leg fighting for the Thai Special Forces during the Secret War in Laos, Sommai now works as a barber in a small shop in a canal community of suburban Bangkok.
