At the beginning of high school, Piper, Sophie, Isabella, and Ono believed that they would always be their best friends, so they sank a time capsule in the lake that listed the things they wanted to do before graduation. By the time they reached their senior year, they had already parted ways. Piper became the clown in the class, a party girl who never drinks. Sophie promised to maintain her virginity before marriage and created a purity application. Isabella is a feminist who is the editor of a magazine. Honor is the pride and joy of the community. Her dream of becoming a professional ballet dancer is being realized. But when a tragedy occurs, the ex boyfriends must reunite, open the spacecraft, and complete their pre graduation wish list.
