Those flat-chested girls who took on the men's swimsuit challenge are now attempting the men's bath challenge! They check into a hot spring inn while dressed as men. Armed with a "secret weapon" learned from their previous failure at the pool, they head into the men's bath. A boyish girl tests her courage with only a single towel wrapped around her waist. She's told that dipping the towel in the tub is a no-no... it might be even more dangerous than the pool (sweat). As the shame-inducing missions become more extreme, will they be exposed as girls once again...!?
