Rumors circulate about a mysterious freedom fighter who wears a Korean bridal mask, roaming the land to combat injustice and deliver righteous judgment. This enigmatic Korean hero is known as "Gaksital." Two Korean brothers, Lee Kang-To and Lee Kang-San, live in this era. Lee Kang-To serves as a police officer for the Japanese in Korea, devotedly serving and respecting Japan while seemingly betraying his origins. Meanwhile, his brother is a loyal Korean patriot who was beaten so severely by the Japanese police that he became mentally unstable. To care for his brother (and others he holds dear), Kang-To needs power and money. How will he acquire recognition from the Japanese and obtain a more powerful position? By catching the legendary Gaksital. The Gaksital and Kang-To serve as perfect foils for each other; their ideals differ. While Kang-To believes it is right for the strong to prey on the weak because the strong worked that much harder to achieve power, the Gaksital believes in equity among all people. And so, the Kang-To (Justice) vs. Gaksital (Justice) cat-and-mouse chase begins. As truths are revealed, friendship and family ties shatter, the people of Korea rebel, and tragedies unfold, resulting in the loss of hundreds of thousands of lives. Lee Kang-To changes from the Japanese's dog to a tragic hero of Korea. This is a tragic story of love-hate, right-wrong, patriotism, betrayal, and redemption.
