K-Drama "Doubt": Cast and its Filming Locations

The drama “Doubt,” consisting of 10 episodes, is a thrilling story about a top profiler confronting the secrets of his daughter, who is entangled in a murder case he is investigating. As he desperately seeks the truth from the depths of despair, the father-daughter duo navigates a gripping psychological thriller.

“Doubt” begins with the challenging question, “What if my daughter killed someone?” This premise sets the stage for a fierce psychological battle between a father who doubts his daughter and a daughter harboring secrets. Ha-bin displays suspicious behavior, even lying to her father, the profiler, without feeling intimidated. As the police investigation unfolds, clues increasingly point toward Ha-bin, leading Tae-soo on a relentless quest for the truth. The tension-filled psychological warfare between the father and daughter becomes a focal point of the narrative.

While the drama “Doubt”presents itself as a unique father-daughter thriller, it also raises profound questions about the meaning of family. Tae-soo, who has been so focused on crime scenes that he neglected his family, now attempts to care for his daughter just as a crisis arises. Compounding the tension are the secrets surrounding Tae-soo’s deceased wife, Ji-soo (played by Oh Yeon-soo). As their relationship deteriorates due to mistrust, the drama delivers a deep message about how much we may overlook regarding the precious people in our lives.
