Taylor (Aly Michalka) and Courtney Callum (AJ Michalka) are two thoroughly spoiled yet well-intentioned sisters whose widower father, Reed Callum (Jack Coleman (actor)), owns Callum Dairy. Taylor has just gotten her license, after almost failing the test at the beginning of the movie. They leave the house to depart for a shopping trip, but leave a towel on the stove, starting a house fire. Shocked by their carelessness, and deciding the girls should start making their own cash, Reed puts them to work at the dairy to teach them responsibility. He goes out of town, looking for a rare butterfly to add to his collection. This leaves the girls to look after the dairy.
