Taylor and Courtney Callum are two thoroughly spoiled yet well-intentioned sisters whose widower father, Reed Callum, owns Callum Dairy. The girls mother died prior to the events of the movie. Their house keeper Corrine helps take care of the girls now. 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 over spending, 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. When the girls start working at the dairy, it quickly becomes their worst nightmare. They mess up almost every step of the way, such as dropping Courtney's cell phone into one of the full yogurt cups, and then tripping and splashing blueberries on themselves. All the employees think they are stuck-up and don't believe that they can do their job. Soon after they start working there and doing their jobs better, someone steals all the money out of the businesses' bank account. It is then up to the girls to come up with a plan to save the dairy, and the jobs of those who are working, but no one believes in them. Taylor has changed her nature and asks Courtney if she can use her party money to pay for the employees' paychecks, or else they will leave Callum Dairy. Taylor and Courtney are at a meeting with the other employees when Taylor tricks Courtney into leaving to get her cell phone, she says that she will get the money, but still no one believes her. Without consulting Courtney, Taylor uses her party money for the employees, thus causing a very big fight between the two of them. Taylor and Courtney finally enjoy their work in the factory and earn the employees' belief and respect. However, Courtney ignores Taylor in every possible way. They have a fight at work when Courtney is putting in the numbers for the expiration dates. Even though they have the money to pay the employees' paychecks, Courtney's mistake threatens their business because the milk, believed to be expired, is sent back. Their employers realize this will take them all night and that they will miss the deadline, but Reed comes along with volunteers, mostly town folks who are impressed with the sisters' efforts to save the beloved dairy company. They manage to pull through the evening and the employees and town folks celebrate. It is revealed that his business partner and best friend Bob Fenwick is the thief, but he gets away with the money. After checking his finances, Reed determines that the dairy will survive, but that money will be tight for some time. The girls happily volunteer to work with him even when he gives them the day off to help out. In an alternate ending, Courtney finds a way to track Reed's friend who stole the money. The girls show their father a footage of the embezzler playing in a casino in Puerto Rico, and Reed alerts the FBI to catch him. Despite getting their money back, the sisters continue working in the dairy in the hopes of one day succeeding their father.
The film received mostly positive reviews from critics. Jeff Swindoll of the Monsters and Critics website said, "Not too bad and a perfect time killer for the kids. I'd suggest a rental for family movie night. Maybe the lessons the girls learn in the will cross over to the audience." Kevin Carr of 7M Pictures said, "Cow Belles follows the Disney formula perfectly. It stars two hot, young singing sensations, who have a contract with the Disney recording branch. If you frequent the Disney Channel often on the dial, you'll recognize Alyson Michalka as Keely from Phil of the Future. These girls are next in line to take over where Hilary Duff and Lindsay Lohan left the stage. Overall, Aly and AJ are decent actors and carry the film as best they can. Aly has a stronger, more mature part, and it shows that she at least has a little more camera time on her sister. However, the casting of the sisters works well as they have good chemistry. Ultimately, these two make a better pair than Haylie and Hilary Duff ever did." Commonsense Media said, "Parents need to know that this film might at first seem to tell kids that the sisters' frivolous lifestyle is desirable and that their carefree, irresponsible behavior is something to aspire to. But things turn around when the girls finally realize the value of hard-earned money, learn about responsibility, and gain respect for people who must work for a living. While adults may not find this quick turnaround believable, the movie's overall intention is good." Ultimate Disney reviewed the DVD saying "Cow Belles has its fair share of flaws but redeems itself with a solid story and a surprise or two by the end. Like the milk in the movie, the bonus features are skim, and the audio/video presentation could use some improvement. The price tag for this one is a little higher than your average DCOM too, so a purchase may not be quite warranted. Still, those who have taken a liking to Disney Channel features in the past should give this one a try, so a rental is recommended.".
