This week's special is called My Bad Girls' Generation. Girls' Generation greets the Running Man members. They form six groups of two, and the remaining three women form a group as well. Among all these women are three bad girls. Who are the hidden bad girls?
This week, the Running Man members continue from where they left off last week. Accompanied by guests Lee Sang Yeob, Lee Da Hee, Hong Jin Young, and Kang Han Na, the members set off to do various missions. At the end, the losers will have to go on a scary trip to somewhere frightening while the winners will get to enjoy the luxury at a wonderful place.
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.
Now that every one has found themselves a partner, it is time to begin the race. However, the members are informed that there are thieves among them. The thieves must not fail the missions if they don't want their identity revealed. Throughout the race, some of them will be given the chance to switch partners. Who will be the one to win the race in the end?
This week's guests are Jang Hee Jin, Bona of WJSN, and Kim Jae Young. Amongst the members and the guests, one secret couple and one relationship virgin are hiding, and the relationship virgin exists to catch the secret couple. As they play games, some members start to act unusual and suspicious. Stay tuned to find out if the relationship virgin manages to catch the secret couple.
