“Doctor John” is a medical drama about doctors specializing in pain management. In a refreshing take on the genre, “Doctor John” will portray the doctors’ search for the cause of their patients’ mysterious pain as a thrilling chase, almost like a detective hunting down the perpetrator behind an unsolved crime. Cha Yo Han is a genius anesthesiologist, who is also the youngest professor at his medical school. The brilliant doctor goes by the nickname “10 Seconds,” a reference to his ability to diagnose his patients in the 10 seconds that it takes for them to enter an examination room and walk to their seat. Kang Shi Young is a legendary anesthesiologist, who was always at the top of her class throughout medical school. The talented doctor inherited her skills from her cool-headed, rational mother, while she inherited her empathy, listening skills, and warm bedside manner from her father.
