Former showbiz stars Roko, Hayu, and Nina live together in a dormitory for dropout idol girls. As timing would have it, young dreamer Sakura happens to move in with the other girls just as an announcement is made to tear down the dorm due to a 100-million-yen debt! This leads to the unexpected formation of a new idol group called Fruit Tart. Their sole mission: earn some yen and stop the demolition.
