It was love at first sight for Emily and Ethan. But then Em lost his number and, with it, all the hope of finding a real boyfriend before the end of senior year. All she knows about Ethan is his first name, that he has a supercute smile, and that he's going to a prom this month. Which high school? That's anyone's guess....

Em enlists the help of her three best friends, who quickly score formal wear and hail a limo. Together, Emily, Max and Sid vow to find Ethan, to find a cure for senioritis, and most important, to find true love -- one hilarious prom night at a time.
