Alyson Michalka and Amanda Michalka star as Taylor and Courtney Callum, two pampered sisters whose father Reed Callum, (Jack Coleman) owns Callum Dairy. Taylor has just gotten her license, after almost failing it at the beginning of the movie. But then their life turns upside down. One day, when Taylor and Courtney return from a shopping trip, they find their kitchen has burned because of them dropping a burner on on the stove, causing the kitchen to catch fire. Deciding now is the time for them to learn the family business, Reed puts them to work at the dairy to show them responsibility about running a business. Their dad goes out of town, looking for a rare butterfly to add to his collection. This leaves the girls to look after the dairy. When the girls start working at the dairy, they are at their worst nightmare. They mess up almost every step of the way, such as tripping and splashing blueberries on themselves, and dropping Courtney's cell phone into one of the full yogurt cups. Soon after they start working there, someone steals all the money out of the businesses bank account. It's then up to the girls to come up with a plan to save the dairy, and the jobs of all the people who work there.
