In 1874, the Handa Silver Mine in Fukushima, once one of Japan's three major mines from the Edo period, is on the brink of collapse. Local noble Hayata Dennosuke, the mine's administrator, faces mounting financial losses and reluctantly decides to transfer control to an outsider: Godai Tomoatsu, a Satsuma-born entrepreneur known for his sharp business instincts. Godai arrives in a community where he is treated as an intruder, regarded with deep suspicion and hostility. History has cast Godai as a villain, but the story digs into the unknown side of his character, showing how he navigates entrenched local prejudices, political friction, and endless misunderstandings. The narrative follows his efforts to rehabilitate the mine through painstaking negotiations, strategic alliances, and sheer determination, while also confronting sabotage and physical threats from those who see him as a threat. Along the way, the series reinterprets a controversial historical figure, offering a humanized portrait of a man battling both material ruin and social contempt. The arc moves from crisis and conflict toward gradual recovery, blending personal drama with the larger story of Japan's Meiji-era industrial transformation.
