1987, Countryside in North China.
Chen Xiaomei, 8 years old, item number 791205; Wang Shuanzi, 12 years old, item number 791211... They should have been children, but they were swallowed up by the "policy" and "digested" into child laborers in Shanxi's black coal kilns.
A lone wolf named "Reaper" used a hatchet to split open the black curtain and avenge the dead; a 12-year-old boy took the microphone and shouted the first "goods number" at the radio station, letting the sun shine into the rotten soil.
From burying knives to raising placards, this is the story of how a group of ordinary people used their flesh and blood to warm up to the laws of fairness.
When the boy no longer holds the sword, dawn truly belongs to the world.
