Chen Hao, a country boy, loses his wife. Following his elders' wishes, he heads to Dongguan to seek refuge with his sister-in-law, Su Wan.
A cramped rental room, a crowded industrial district, and beneath the neon lights, the rawest struggles of the working class.
To protect Su Wan, he beats up a supervisor and is chased until he has nowhere left to run.
To survive, he takes day labor, hauls heavy loads, and gets mixed up in the underworld. From the lowliest factory hand, he fights his way up step by step.
Underworld feuds, brotherhood, and deep bonds with factory girls: through blood and tears, he finds his footing.
