The story, without the spoilers.
Baek Hee-sung seems like the perfect husband and father: gentle, hardworking and devoted to his wife and daughter. His wife, detective Cha Ji-won, loves him completely. Then a serial murder case lands on her desk, and the clues begin pointing toward a man from a dark past — a man who looks very much like her husband. Hee-sung insists he has no memory of his childhood and no connection to the crimes, but is he lying, or is he a victim of something even stranger? Flower of Evil is a masterclass in tension. Every loving scene between husband and wife carries a second meaning, and Lee Joon-gi is superb as a man who may be innocent, guilty, or something in between. The romance and the thriller are not separate stories here; they are the same question. Can you love someone you cannot fully trust, and can a person change who they truly are?
A little curiosity. A new favourite.
