Synopsis
Mouse Season 1 follows Jung Ba-reum (Lee Seung-gi), a rookie police officer, and Go Moo-chi (Lee Hee-joon), a seasoned detective, as they hunt a psychopathic serial killer dubbed the Head Hunter, who terrorizes South Korea with brutal murders.
Their investigation intertwines with a moral dilemma: Dr. Daniel Lee (Jo Jae-yun) advocates for fetal genetic testing to identify psychopaths, sparking debates about ethics and free will. Flashbacks reveal Moo-chi’s traumatic childhood, where he survived his family’s massacre by the Head Hunter, and Jae-hoon (Lee Seung-gi), a neurosurgeon framed for the crimes, whose innocence is questioned by his wife Ji-eun (Park Ju-hyun).
The season culminates in a shocking revelation: Jae-hoon is the Head Hunter’s son, driven by a genetic predisposition to violence, while Moo-chi’s quest for justice becomes a vendetta against his own brother.
