Mouse

Set in a world where genetic testing can identify psychopaths in the womb—even distinguishing between psychopathic predators and geniuses—"Mouse" follows Jung Ba-reum, an upright and kind-hearted rookie police officer whose life is completely upended after a harrowing encounter with a vicious serial killer. Teaming up with Go Moo-chi, a hardened detective bent on avenging his parents' murder, Ba-reum dives into a relentless manhunt that forces them both to question the nature of evil, human genetics, and whether psychopathy can truly be predicted or prevented. As the investigation deepens, the series weaves a complex web of deceit, shocking twists, and medical conspiracies that challenge everything the characters thought they knew. The line between good and evil blurs dramatically, culminating in a psychological thriller that explores the heavy moral and ethical dilemmas surrounding crime, punishment, and the innate darkness hidden within human society.
