Three girls in a cramped club room decide to go camping, and somehow that's enough. There's no plot twist, no crisis, no reason to care beyond watching them eat food, complain about the cold, and fall asleep in a tent together. Room Camp knows that the coziness is the point, and it doesn't waste a second pretending to be anything else.

Three girls in a laid-back outdoor club, which meets in one corner of a classroom at a high school in rural Yamanashi Prefecture, find themselves pulled into an unexpected adventure. Nadeshiko shows up hoping to kill some time in the club room, but her clubmates Chiaki and Aoi suddenly announce that they are all going on a trip. A talk about what makes someone a true Yamanashi local leads to a kids' stamp rally, and the promise of a year's supply of Minobu steamed buns wins Nadeshiko over. The trio travels across the prefecture, collecting stamps, sampling local treats and seeing what the region has to offer, while the question of where the journey finally ends hangs over it all. Expect short episodes of light comedy and easygoing slice of life.
