It's the 300th episode of Running Man. The members must complete various missions relating to the number '300' in celebration of the 300th episode. For each mission that is completed, the members receive a puzzle piece. Each mission requires the members to face a strong opponent. Will the members be able to show their teamwork and beat these opponents for the puzzle pieces?
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.
This week, the Running Man members take a break from the Family Package Project and have TV Rating Notice Race Part Two. Not only will the winner get to direct the five-second tv rating notice, but they will also be allowed to handle the poster and photo on Running Man's official website. Furthermore, the posters will be distributed all over the broadcasting station. Each of the members draws their own creative vision for the rating clip. Ji Hyo plans to dress everyone up as kaonashis, while Jae Seok is inspired by "The Greatest Showman". So Min forgets to add Seok Jin to her clip! Who will win the race and become the director for the next TV rating notice?
The members of Running Man have been together for eight years now. But how well do they know about each other? This week, the members must choose the most suitable person to carry out the mission presented to them. If everyone succeeds, it's a happy ending. If not, a penalty awaits the members.
