Four male celebrities in their 40s who have no experience in group travel, except for school field trips and business trips, go on a fully pre-planned group tour. They depart lightheartedly without serious preparations, but their busy travel schedule, led by the guide, is not something to be taken lightly! They have to do everything – eating, sleeping, and sightseeing – together with non-celebrity travel mates they never met before, which adds a unique twist to the travel adventure.
