Description: 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?
