After their graduation ceremony, the graduating class decides to take a little trip to celebrate their freedom. One of their friends, a rich father, is funding the whole thing. There are 15 of them, seven girls and eight guys. They decide to check out their room, which has a balcony. The balcony makes the room look like a neighbor's, and the girls think it's a good idea to check it out. The next morning, they find that one of the girls has mixed up all of their shoes, and that someone else has paired them up.
