Actors Yoo Hai Jin, Jin Sun Kyu, Park Ji Hwan, and Yun Kyun Sang are heading to Europe for their camping trip! Being half worried and half excited, they make it to Zurich, Switzerland, their first stop of the trip. They are overwhelmed by the impressive and phenomenal sceneries as soon as they arrive. Hai Jin shows Sun Kyu and Kyun Sang around the Interlaken, and they spend an unforgettable evening at the campground.

Hai Jin offers Sun Kyu and Kyun Sang a chance to try paragliding. They have a great and unforgettable experience flying in the sky of Switzerland and enjoy the magnificent views from the above. After paragliding, they go grocery shopping and have lunch at Lake Thun. Later, they head to a new campsite in Grindelwald.

Hai Jin, Sun Kyu, and Yun Kyun Sang arrive at Grindelwald, their second campsite in Switzerland. They have a pork belly party in front of the majestic view of the Alps. After spending a night at the campsite, they set off from Grindelwald and through the mysterious nature, they will begin their journey to Italy.

They wrap up their last day in Switzerland and get ready to go to Italy. By passing through three passes with eight-hour driving, they finally cross the border and make it to Italy. What kind of a day will unfold outside the tent in Italy? Meanwhile, Ji Hwan finally joins the trio, the moment they’ve all been waiting for.

To welcome Ji Hwan, they go on a trip. They visit Parma, the city where parmesan cheese was born. The members start to have a stomach ache all at the same time, but they are completely cured after eating one spoon of natural Italian digestive medicine.

The four brothers enjoy a breathtaking view as they wake up on top of the Italian mountains. After a relaxing morning, thanks to Ji Hwan’s camping expertise, they head to Florence. They splurge on a fancy steak lunch and head to the plains of Tuscany where they are greeted by animals of all kinds at their next campsite.

The members have a hard time falling asleep all night due to a mysterious noise which turns out to be a very cute disruptor. The next day, while they’re having breakfast, a donkey, an elk and seagulls show up and interrupt them

Ji Hwan decides to make a delicious dish for the members who are tired after trekking all day. He prepares samgyejuk so the members can get recharged. Meanwhile, the members get surprised by who made the rustling sound and Ji Hwan drives for the first time.
