Lincoln High School is a school full of all kinds of new people. Perhaps in this rapidly developing 21st century, studying hard is no longer a top priority, and fashionable men and women are more keen to enjoy the fleeting life of youth. Diana Weston (Mary Sheldon Marley Shelton), Hannah Ward (Rachel Blanchard), Kansas Hill (Mena Suvari), Lucy Whitman (Sara Marsh) and Chloe Miller (Melissa George) are cheerleaders at Lincoln High School and a bellwether of school fashion. They have different personalities, but they are United as one and are an indispensable backbone of cheerleaders. However, one day Diana and the team's quarterback Jack Bucklitt (James Marsden) went off with their guns and got pregnant. In order to help friends who were kicked out by the school and their parents, the other four sisters took turns to take care of Diana and even tried to rob a bank.
