The film opens after school on Tiffany's 18th birthday. She and her friend Gabriella encounter Tiffany's dad Brian and brother B.J. outside the school. It seems that Brian always picks her up from school on her birthday wearing a birthday hat. Tiffany's mom, Brian's ex-wife Debrah, arrives and she and her new husband Calvin surprise Tiffany with the car she wanted (and hoped her father would give her), but she can't drive it well. She and Gabriella drive it to the frat house, where they hear that Jonathan and the others are having a Halloween party at Lake Derrick. She hopes to make it up to them for ruining the previous year's party. Jonathan invites her. Brian finds Madea, Joe, Bam, and Hattie at his house to surprise Tiffany; she's underwhelmed. She sees her friend Leah and tells her about the party. Tiffany asks her mom if she can go to the party. She says yes to upset Brian, but he lets her go there to teach her a lesson..
