Lee Bo Young and Lee Min Ki lead the gripping medical mystery drama Mary Kills People, premiering August 1 on MBC.

There will be serious discussions about life, death, and choice sparked by a new K-drama. The South Korean version of the critically acclaimed 2017 Canadian television series, Mary Kills People, will debut on MBC TV on August 1, 2025. Lee Bo Young, Lee Min Ki, and Kang Ki Young are the main characters in this suspenseful medical black comedy, which combines moral quandaries with emotional depth.
Mary Kills People: What Is It About?
Woo So Jung (Lee Bo Young), a seasoned emergency physician who covertly assists terminally ill people in ending their lives through euthanasia, is the focus of the drama. A colleague medical expert, portrayed by Kang Ki Young, helps her on this covert expedition by lending his expertise to her cause.
The appearance of Jo Hyun Woo (Lee Min Ki), a detective with a deadly brain tumor, causes the plot to take a dramatic turn. A tense cat-and-mouse dynamic emerges as he starts to suspect Woo So Jung's covert practice after looking into a series of unexplained disappearances.
Significant issues of life, death, and autonomy are brought up in the series. Should the sanctity of life always take precedence, or should people have the freedom to decide when and how to pass away?
