David Foster is a rich and happily married mad. However he has a huge problem: his two step sons who do nothing else than spend his money, wreck his stuff and annoy him. So he has decided to encourage Brody and Brandon to move out.

The boys come up with yet another idea how to make some money, while David tries to take Brody along to work and show him how much fun it could be.

David cuts off all the boys' services in the house like maids and chefs. In order to get back at David, the boys hire their own staff. To finance the project they have to come up with a new plan and see the perfect opportunity has come.

David takes the war to the next level and tows Brody's car to Phoenix. In order to get the car back, the boys take his plane to fly there, but stop in Las Vegas to party first. As David has another move to make, the boys have to come up with something else to hit back.

David starts to enjoy his war against the boys. While they win the first round, they lose the second one. But who will score in the last one?

Spencer once again has an idea how to raise money for the boys by using David's career - as their plan is going badly, they need David to save them - but how to do that without him knowing?
