Third-year high school student Jamie Young is in love with his childhood friend and classmate, Sandra McBerger. Thus, he hopes to be paired with her for the marriage practical: their school's practice of randomly selecting boy-girl pairs to live as pretend married couples while monitoring and rating them on how close they have gotten. Meanwhile, the lively Annabella Watkins wants to be assigned to her crush, the popular and good-looking Michael Todd.
Much to their dismay, Jamie and Annabella find out that not only have they been paired together, but so have Sandra and Michael! Determined to be with their crushes, Jamie and Annabella strive to earn as many points as possible, as the top 5 pairs earn the right to switch their partners—so long as both couples agree.
