John Tucker is popular, sexy, talented and a complete player. He dates three girls at once, the total stereotypes of every high school: the cheerleader, the brainiac and the slut. When a new, very pretty, sweet and clever girl, Kate, comes to town after her mother's heart is broken and she packs their lives up yet again, they set out to use Kate in their scheme to humiliate John. But this fails and he breaks up with them after "finding his emotional needs". Now they seek to kick the gear to overdrive and use Kate to break his heart and be the ultimate challenge for him.
