The story, without the spoilers.
Jung Ba-reum is a sincere young police officer who believes good people can stay good. Detective Go Moo-chi is his opposite: rough, angry and driven by the childhood murder of his parents. When a series of brutal killings shakes the city, their paths cross, and the drama asks a disturbing question — can a psychopath be identified before birth, and would stopping them be justice or murder? Mouse is a dark, twist-heavy thriller that constantly reframes what you think you know. Just when you settle on a suspect or a theory, it pulls the ground away. Lee Seung-gi gives a fearless performance that breaks his nice-guy image completely. The violence is heavy and the middle episodes are dense with reveals, so this is not light viewing. But if you love a crime drama that respects your intelligence and keeps you guessing until the end, Mouse is one of the best of its kind.
A little curiosity. A new favourite.
