Lee Bo-young Returns in a Dark Medical Thriller

Acclaimed actress Lee Bo-young has taken on another bold challenge in the genre drama space. With her intense performance, she's already gaining attention.

MBC-TV's new Friday–Saturday drama "Mary Kills People" (written by Lee Soo-ah, directed by Park Joon-woo) premiered on August 1, drawing a nationwide viewership rating of 3.2%, according to Nielsen Korea.

A Controversial and Shocking First Episode

The debut episode introduces Woo So-jung (played by Lee Bo-young), an ER doctor at Bunsung General Hospital, and Choi Dae-hyun (played by Kang Ki-young), a former plastic surgeon. Together, they assist terminal patients who choose death over suffering.

The opening scene was already controversial: the pair help national soccer hero Choi Kang-yoon (played by Lee Sang-yoon) die, but when he briefly regains consciousness, they smother him with a pillow. They also advise Jo Hyun-woo (Lee Min-ki), a late-stage cancer patient, on assisted death.

Police Closing In

Meanwhile, the police begin closing in. The episode ends with a case board showing both Woo So-jung and Choi Dae-hyun labeled as "suspects in a serial drug-assisted murder case," setting the stage for a gripping investigation.

What Is "Mary Kills People"?

"Mary Kills People" is a medical thriller that explores the gray area between life and death. The story revolves around doctors who help patients in terminal conditions die with dignity—and the detectives pursuing them.

The drama airs every Friday and Saturday at 10 PM (KST) on MBC-TV.
