The first teaser for tvN's upcoming drama "Ghost Doctor" (literal title) has been released!

"Ghost Doctor," directed by Boo Sung Chul ("Heirs"), is a fantasy medical drama about two doctors who are worlds apart in terms of their histories, skills, and personalities, but who end up merging bodies and spirits. Rain will play Cha Young Min, a brilliant thoracic surgeon, and Kim Bum will play silver-spoon resident Go Seung Tak. Despite studying medicine, Apink's Son Naeun will play emergency department intern Oh Soo Jung, who believes in mystical phenomena and miracles.

Cha Young Min's spirit controls Go Seung Tak's every move from within his body in the new teaser, almost as if he were controlling a vehicle. Meanwhile, in the operating room, Go Seung Tak maintains a blank expression as he moves robotically in response to Cha Young Min's commands—then gives Cha Young Min an angered glare as the arrogant surgeon tries to point the scalpel in his direction.

"A body-rental medical drama," Rain says in voice-over at the end of the clip. The first episode of 'Ghost Doctor' will air in January."

The first episode of "Ghost Doctor" will run on January 3 at 10:30 p.m. KST. Meanwhile, have a look at the new teaser below!
