David Devereaux Blackmore the grandson of Blanche Devereaux, and the son of Blanche's daughter, Janet and her husband, Michael .
Janet and Michael decide to take a second honeymoon in Hawaii to work on their problems with their marriage, and they have David stay at Blanche's house because he has become too rebellious. When Blanche picks him up at the airport, he was nowhere to be found, only to be sent home by a policeman, saying he stowed away on a plane to the Bahamas while going to the bathroom. David refuses lunch and decides to eat at a restaurant instead.
At 2 AM, David wakes everyone up with loud music, and they find David in the living room with some new "friends" he made from a pizza joint. Dorothy throws David's "friends" out of the house, and tells David she's having a real problem with his attitude. David tells everyone they can just kiss his attitude, and Sophia slaps him across the face. Stunned, David runs outside. Blanche goes outside on the porch to talk to him. David tells her no one ever hit him before, and that his parents fight all the time, making him feel neglected. The next morning, he is given a long list of chores to do as punishment.
When David decides to sneak out of the house to have his own life, Dorothy catches him and talks to him. Dorothy asks David if he's just going to "wimp out." He denies "wimping out" and says he doesn't have to stay at his grandmother's house, especially with the crappy chores - he even says that vacuuming is for girls. Dorothy replies that life is full of crappy stuff to do. She then tells him that his grandmother loves him. David tells her life stinks, and Dorothy said that he had a choice, either to tough it out or let it beat him, but right now, he's at his grandmother's house and things don't have to stink. If he stays and works at it, and everything turns out okay, he'll have a place to go to when things at home really get to stink. David comes to trust Dorothy, and he walks back into the house while she fixes him something to eat.
The next evening, Blanche proposes a toast to Dorothy who got an A on her test. Dorothy then continues with another toast to David, saying that in the past week, he has proven that he is really a good kid. David then decides to stay for good, and Blanche calls Janet saying that she wants to keep him and raise him herself. Janet refuses and wants to take him home, and Blanche tells Janet that: "If she and her husband don't straighten up, she'll kick her uppity butt 'till Hell won't have it again!" After hanging up the phone, Blanche says she meant every word she said. David goes to Hawaii to join his parents to make a new start in their relationship.
