The ₩20 billion-budget historical drama charts the life of Kim Su-ro, who unified 12 small countries to become the legendary founder and ruler of Geumgwan Gaya, the city-state of the Gaya confederacy which dominated sea trade and iron working during the Three Kingdoms Period in the 5th century. Kim Su-ro's fiery temperament, charisma and intelligence are his only defense in an extended political struggle, with competition for the throne from his half-brother and lifelong rival, Ijinashi (first king of the state of Daegaya), his former friend Seok Tal-hae, and the dangerous ambitions of Shingwi Ghan.
