Director Na Young Seok plans to send Jung Woo, Cho Jung Seok, Kang Ha Neul, and Jeong Sang Hun to Iceland without any extra clothes or luggage. They are first asked to have dinner in Gangnam-gu as a meeting, however, the dinner turns out to be their last meal in Korea before they fly to Iceland.

Three Dummies make a journey to their way to Gullfoss. During their first attempt, the weather gets bad, and they head to Hallgrimskirkja, a beautiful church. They eventually make it to Gullfoss and are in awe due to the beautiful scenery. Meanwhile, Kang Ha Neul joins the group.

Ha Neul joins them, and they have become Four Dummies. Before going hiking, they visit a flea market to buy clothes and shoes for the journey. They also decide to go Geysir, a famous hot spring in Iceland. However, the weather is very cold, and soon, it will be dark. Will they decide to go or not?

The Four Dummies continue their journey in Iceland. After a long day in the wilderness, they finally get to see the Northern Lights in the city of Vik. They are once again stunned by the beauty of Mother Nature and think of their loved ones back in Korea. For the first time, they enjoy a meal at a local restaurant and fall in love with its exotic dishes.

Everything in Iceland continues to fascinate the four dummies, and this time, they visit Jokulsarlon to see the icebergs and a beautiful ice cave that formed hundreds of years ago. At night, they drive out to see the Northern Lights again, and they enjoy themselves stargazing and making new memories together.

The cheerful members meet a fierce snow storm on their road to Reykjavik. The harsh weather condition delays their journey for a while but it does not stop them from moving forward. Once they reach Reykjavik, Sang Hun has to return early to Korea for his work, so they decide to throw a small good-bye party for him. For the last part of the journey, they split up and spend time individually to visit places of their own interest.

The four dummies complete their special trip to Iceland and back to Korea. However, the staff of Youth Over Flowers invite everyone to famous sausage restaurant in Seoul to celebrate their trip to Iceland, and hands them special gifts. Also, unrevealed scenes from the trip are ready to be aired as well! Stay tuned to check the last episode of Youth Over Flowers.

Producer Na Young Seok goes to Phuket where the cast of “Reply 1988” is having a celebratory vacation. And he makes a prank on Jun Yeol, Jae Hong and Kyung Pyo and takes them to Africa to shoot “Youth Over Flowers in Africa”. Bo Gum who had to return from the vacation to Korea for a music show filming also joins the trip. The young actors manage to arrive in Namibia with few clothes, and they need to deal with many things from booking hotels, hiring a car, exchanging money to planning their journey.

Although Bo Gum misses his flight, he manages to arrive safely in Namibia and joins the others. Their first destination is Sossusvlei. On their way to Sossusvlei, they get to see beautiful sceneries of Africa and take many photos. They are excited about having a camping in the middle of African desert for the first time in their lives. Jae Hong cooks for the others who are tired from a long drive.

The young actors now head to a resort city, Swakopmund, where golden desert and the Atlantic Ocean meet. Bo Gum tries driving but he can’t help but give up just in three minutes for a reason. In Swakopmund, they find a fancy restaurant that serves delicious but rather expensive dishes. After enjoying the luxury, they begin to worry about their budget. Will they be able to make it to their final destination without a problem?

After having relaxing days in Swakopmund, they hit the road again to see wild animals this time. They head to Etosha National Park which is known as home to numerous kinds of wild animals. They are surprised by an appearance of a wild animal at the entrance of the park. For the second camping in Africa, Jae Hong cooks again. While having dinner, they bring back their old memories and talk about their career and friendship.

In Etosha National Park, they enjoy a variety of activities such as Game Driving. They are impressed to see the Etosha pan, a large endorheic salt pan. To celebrate the last night in Namibia, Jae Hong makes Tomato Pasta and Bo Bum brings an exotic African alcoholic drink. On the next day, they finally get to the final destination, Zimbabwe, but it is already in the afternoon when Victoria Falls is closed before sunset. Will they be able to tour Victoria Falls before it is closed?

Seeing the great view of Victoria Falls, the four young actors recall their memories for the last 11 days in Africa and they become emotional. They go rafting on the Zambezi River and enjoy one of the most thrilling experiences in their lives. Jun Yeol and Bo Gum move to do a bungee jump while the others give up.

A tent and camping equipment are set up on a rooftop of a building in Seoul. About a month after the trip in Africa, the members of Youth Over Flowers in Africa are gathered again. The camping equipment reminds them of their memories in Africa. They talk about everything they experienced in Africa from people and animals they met and the food they had. Plus, behind the scene stories are revealed.

Director Na Young Seok and the whole staff plan to kidnap WINNER despite the group already knowing the program. Step by step the staffs ask help from managers and even try some tricks, but the members are way too cautious of every detail. Later creating a fake commercial shooting set staffs hope WINNER will fall for this one, this time.

The four members leave Perth and head off to a serene port city, Fremantle, by trying out public transportation from buses to trains as a true backpacker. Enjoying the getting-lost-free journey with ‘Map Seung Yoon’, the four young gentlemen dive in to the living of a West-Australian life.

Third day of traveling and the youths seem to be having a great time, until money gets in the way. The struggle of satisfying all four members with a tight budget is not so easy and Seung Yoon is not the only one who’s stressed out about it. Over a pair of pants and over a pack of corn, the four members wrestle to keep it cool throughout a trip they only dreamed of.

As the West Australia adventure comes to an end, the four youths head to another special experience. This time it’s a whale-watching tour, where you can see real wild whales swimming in front of your eyes. At nature’s grand scene, the members tear up thinking of their past and struggles as a K-POP idol group.
