Running Man are told they can go anywhere on a train and are asked to write down where they'd like to go. Suddenly guards come out and force them to write down "Prison". They have to face a unique challenge per carriage on the train. If they fail, they are sent to prison.
Running Man has become a series of lies and betrayals. As a result, the members will pay for their sins on today's race. They will be put into prison throughout the course of the race for the sins they have committed, and they can only come out when they have served their time. The last member to finish serving their time will have to self-punish themselves with a water bomb. Who will be the member who will get the penalty?
This week, the members and two guests are given 100,000 dollars. In order to win their share in the end, they must try not to spend the money and save as much as they can while being locked up in individual rooms. In the middle of the mission, Jae Seok realizes he has a secret mission to accomplish with an assistant.
