Our 229th Running Man adventure starts with guest Lee Seung Gi getting his very own spy mission. He is to eliminate all the members and guest Moon Chae Won in secret – a classic Running Man spy mission. But he won’t be alone – famed grump Lee Seo Jin will be joining him to complete the mission. True to form, Seo Jin doesn’t seem to be too thrilled about it, and suggests that Seung Gi eliminate him first. They will only be able to eliminate the other members when the two spies are together, but if anyone else catches on, they will fail the mission.
