Denis Cooverman wanted to say something really important in his high school graduation speech. So, in front of his 512 classmates and their 3,000 relatives, he announced: "I love you, Beth Cooper."It would have been such a sweet, romantic moment. Except that Beth, the head cheerleader, has only the vaguest idea who Denis is. And Denis, the captain of the debate team, is so far out of her league he is barely even the same species. And then there's Kevin, Beth's remarkably large boyfriend, who's in town on furlough from the United States Army. Complications ensue.
