Plot[ edit ] In , middle school student Donny Berger is in detention and begins a sexual relationship with his teacher, Mary McGarricle. When this relationship is discovered, she is sentenced to a maximum penalty prison term of 30 years, where she is revealed pregnant.
Custody of the unborn child is given to Donny's abusive father until Donny turns 18 to assume full custody. In , Donny is a broke, alcoholic slacker who spends his time with his friends, local drunk Kenny, bartender Brie and her stripper mother Champale.
Donny is now estranged from his son Han Solo who, embarrassed by his parents' scandalous past and also Donny's immaturity, has changed his name to Todd Peterson to avoid discovery of his parentage. In spite of this, Donny realizes that he may need a back-up plan should Tubby Tuke lose. Donny arrives at Cape Cod to try to convince Todd to participate. Todd had previously told people his parents were dead, so he introduces Donny as an old friend.
Donny quickly becomes well-liked by the others, much to the chagrin of Todd and at the expense of his popularity. Donny tries to convince Todd to see his mother at the women's prison, without revealing that it is for a TV show, but he refuses.
Todd fights constantly with Donny about his father's immaturity. Donny admits his mistake by revealing he was young and didn't know how to be a father since his own never taught him how. Todd eventually imitates his father's behavior, including engaging in a fight with Father McNally, cancelling the church rehearsal. Before Jamie's family could blame Todd, Donny saves him by convincing his future in-laws to have the wedding rehearsal away from churches because Todd is still going through a tragedy from one that killed his parents.
Donny joins Todd and his friends at Todd's bachelor party, a relaxing day at a spa. However, Donny convinces the guys to attend a strip club where over the course of the night, Todd eventually agrees to meet his mother at the women's prison.
Donny, knowing a TV crew will be there tries to stop the meeting, but Todd goes anyway. As Mary, Donny, and Todd have a personal moment with each other, they are ambushed by Randall Morgan's TV crew, forcing a disgusted Todd to leave without signing a release form, leaving Donny without any money. Donny overhears Jamie on the phone with Todd's boss, Steve Spirou, having a conversation that implies they've been sleeping together behind Todd's back.
He tries to warn Todd, but Jamie comes up with a convincing cover story that fools Todd. With some encouragement from Kenny, Donny attempts to patch things up with Jamie, but instead discovers her with Chad having sex at a hotel room. Despite Jamie's hush money, Donny has to stop the wedding. With the help of Vanilla Ice , his friend from his celebrity days, they make it to the wedding in time. Donny reveals himself to be Todd's father, rips up Jamie's check and forces her to admit her actions behind Todd's back.
Todd breaks up with Jamie, accepts Donny as his father, and takes back his birth name of Han Solo Berger. At the strip club the following day, Han reveals himself to be dating Brie and offers Donny the money to pay for his unpaid taxes.
Donny turns down the offer, accepting it's time for him to take responsibility for his actions. Adam Sandler as Donald "Donny" Berger.
