Jen, Liz, and Cat (pictured above from left to right) are 18 year old high school seniors and best friends, having a slumber party as they contemplate their upcoming high school graduation and all of them going to different colleges. They invite their fourth childhood friend to their slumber party. Each of the girls has had a long going crush on this person and they plan to ambush them at the party and profess their love, and in the process, lose their virginities before college.
