The female employees of 765 Production Studio are anxiously getting ready for the Vacation Island International Music Festival. The festival promises many days of pleasure for everyone when combined with an amusement park and a luxurious resort. That is, until their producer says that there is only space for one unit to take part. One of the three groups is chosen to participate in the International Music Festival, where they are given a three-day vacation before taking the stage in the festival's concert, in three alternative situations in which everyone is divided into three groups. Each group of girls enjoys the festival in its own unique way, eager to participate in the much awaited performance, from the time they walk off the boat until the major event.
