Quiet teenager Marc Hall arrives as a new student at Indian Hills High School in Agoura Hills, California. Soon after arriving, he is befriended by fame-obsessed Rebecca Ahn. While at a party at Rebecca's house, Rebeca persuades Marc to sneak away with her and the pair check unlocked vehicles on the street, taking valuables such as cash and credit cards. The two begin hanging out after school, and Marc begins to see Rebecca as a sister figure. When he briefly mentions that one of his wealthy acquaintances is out of town, she encourages him to join her in breaking into his house.
