In the 1990s, Chen Mo was just an orphan who rode a three-wheeler to collect scraps. His biggest wish was to save enough money to treat the disease of his adopted sister. Until the foreman asking for wages forced him into a dead end, he grabbed the rusty wrench and knocked on another door of destiny.
From "mediating" disputes for casinos, to taking a share of the old city renovation; from being discarded as a chess piece by the boss, to becoming the "just right knife" between the various forces.
