Britney Allen, played by Hayden Panettiere, is the captain of the Pacific Vista High School cheerleading squad in Bring It On: All or Nothing. She's very excited about an upcoming cheerleading competition. Why? Because the winning squad will be featured in pop-star Rihanna's upcoming television special to be telecast around the world. Unfortunately, Britney's excitement turns to misery when she learns her father has lost his job and her family must relocate to Crenshaw Heights.   

Britney enters into a pact with her squad, promising never to cheer again. If she breaks this pact, she will be viewed as a “cheer whore” by everyone including Winnie (Marcy Rylan), her replacement as captain of the squad. Winnie lost to Britney, coming in second place when the squad voted for Britney. Not wasting any time, Winnie goes after Allen’s boyfriend, All-American high school quarterback Brad Warner (Jake McDorman), who has made her his “study partner.” But Brad still sees Britney, who lives only an hour away.

Britney’s first day at her new school in Crenshaw Heights is a complete and total disaster. She doesn't relate to anyone there and gets into a confrontation with Camille (Solange Knowles-Smith), who just happens to be captain of the school's cheerleading squad. Later, Camille challenges Britney to show her and the squad her cheerleading moves. Although offered a position on the squad, Britney turns it down. When Camille tells her 100 girls would jump for an opportunity to be on the squad, Britney responds that she should have no trouble filling the spot if that's true. Camille knows she needs someone on the squad of Britney’s caliber to win the competition, so she gives Britney two options: either watch practices from the bench or participate. 

Britney notices the boys on the squad, including Jesse (Gus Carr) -- who secretly pines for her -- engaged in what looks like a violent activity, but they were simply practising freestyle moves called krumping. Britney has the boys teach krumping to the squad, and these moves are added to Camille’s routines during her absence, much to her chagrin. However, Camille comes to realize that krumping is the only way to win the competition. Will she swallow her pride and approach Britney for help?

Directed by Steve Rash, Bring It On: All or Nothing boasts stunts, gymnastics, and awesome dance moves perfectly executed by a talented and athletic ensemble. Although Panettiere and Knowles-Smith are spot on with their dance and gymnastic work, they give uneven performances in other areas. And Alyson Fouse’s screenplay is weak with characters that are not fleshed out. It's particularly disappointing that we never see what drives the main character's passion for cheerleading.
