Hairdresser Peaches Whitaker (Mo'Nique) and her estranged sister, Angela (Kellita Smith), reunite when Peaches travels to Beverly Hills to work in her sister's chichi salon. But Angela soon learns that Peaches is running from the Internal Revenue Service (she owes $50,000 in back taxes). Now the siblings must band together to fend off a rival salon owner (Gina Torres) and save Peaches by vying for a big cash prize at the town's annual hair show.
