The story, without the spoilers.
Lee Yoon-sung was taken as a child and raised in secret by a man seeking revenge against the officials who betrayed his comrades. Trained in combat, languages and technology, Yoon-sung returns to Seoul as a carefree young man working in the presidential Blue House — and by night, as the City Hunter, a mysterious figure who exposes corrupt politicians and steals back what they took. When he meets Kim Na-na, a brave bodyguard with her own painful past, his carefully planned revenge begins to crack. City Hunter is a fast, stylish action romance based on the famous manga. Lee Min-ho is at his most charismatic, the action scenes are sharp, and the revenge plot is satisfying without being cruel. The romance is warm, the villains are satisfyingly corrupt, and the Blue House setting gives the story real scale. Some twists are familiar, but the energy and star power make it one of the most entertaining action dramas of its era.
A little curiosity. A new favourite.
