The last sample of the "Tyrant Plan" suddenly disappeared due to a delivery accident, and people with their own ulterior motives started chasing each other to grab the sample. The one who led the "Tyrant Plan" was the very fierce director "Choi Guk-jang" (played by Kim Seon-ho) who was affiliated with the state agency. He has been secretly operating the "Tyrant Plan" in private, but he didn't know that there were many unknown things hidden behind it. Cha Seung-won plays "Lin Sang", a former key figure responsible for eradicating the forces related to the "Tyrant Plan", and his role will exude an irreplaceable sense of existence.
