Both dramas tell about criminal and how they solve the mysteries with the help of forensic doctors. The forensic doctors played the biggest role in the drama and they acted like the real detective here. There were no prosecutor in Unnatural but in general they are the same.

The plot is very similar, about a group of students who is locked up in school and need to solve the quiz to be able to survive
