An arrogant, domineering bald thug roams around picking fights and bullying his neighbors, throwing his weight around and constantly making trouble for others with his endless misdeeds. A-Nan, a man with a strong sense of justice, witnesses the injustice and steps in decisively. He punishes the villains to their faces, lays down the law, and crushes their swaggering arrogance, using hardcore methods to uphold justice and clean up the toxic atmosphere. This drama is an anthology series, with protagonist A-Nan threading together the overarching mainline; each episode's story is independent and complete, with a self-contained plot per episode, while the whole series shares a unified worldview and theme of justice—each episode tells one tale of rooting out evil and promoting good.
