The beginning starts in the Shooting Star gym. McKenna is practicing her backhand spring on the beam. Coach Isabelle tells McKenna that the move she was doing is way too advanced. McKenna tries to protest, but loses. Then coach tells her to just stretch. As McKenna is feeling depressed, her best friend Toulane comes over and tells McKenna she was great. She then gets on about how the two of them will get into the Olympics in 2016. Toulane explains that she will be on the podium with her gold, and McKenna next to her with her silver. McKenna tells her that she will get a gold instead. The two get back to gymnastics until McKenna's grandma comes into the gym with McKenna's twin younger sisters, Maisey and Mara. The four of them leave the gym.
At home, McKenna, Maisey, Mara, Mr. Brooks, and Mrs. Brooks are at the table and talking about Mrs. Brooks buisness, and how her guitarist quit on her. Mr. Brooks tries to convince Mrs. Brooks to let his old rock band play at her coffee shop. Then, Mrs. Brooks tells Maisey and Mara to go to their room while she and Mr. Brooks talk to McKenna. When the twins leave, McKenna thinks it is about her accidentally feeding the class pet. Mr. and Mrs. Brooks explain that Mr. Wu E-Mailed them and said that McKenna's grades were slipping and he recommended that she get a tutor because he's concerned about McKenna. McKenna refuses and promises to bring her grades up as there's going to be a science quiz the next day. She starts to read the science book, but doesn't understand it and quits.
At school McKenna is desperate to improve her grades and ends up cheating off of Sierra's paper. McKenna gets caught by Mr. Wu. As soon as her parents find out McKenna's grounded and they tell her that unless she gets a tutor she'll have to quit gymnastics. Mr. and Mrs. Brooks also scold McKenna for putting gymnastics before school and for setting a bad example for the twins by cheating. McKenna reluctantly meets Josie at the school's library. When McKenna sees Sierra, she tries to hide. Josie doesn't understand this. After Sierra leaves, Josie tries to tutor McKenna. McKenna gets angry when she finds out Josie wants her to read "baby books". She storms out of the library and asks Mr. Wu to find her a new tutor. She tries three different tutors who won't work for her. McKenna is soon forced to go back with Josie.
At the presentation run, the Shooting Stars gymnastics team preform for the parents. When McKenna goes up, she does everything perfectly. She comes to the very end of her practice, and decides to disobey the coach by doing the backhand spring. As a result of her disobedience McKenna falls and breaks her ankle. When McKenna comes home, she is very angry, as her parents say that the accident will allow her focus on school now instead of gymnastics. McKenna yells at them saying they must be happy she broke her ankle, and runs into her room. She tears down most of her posters, and cries. The next day, McKenna comes to school, and Mr. Wu tells McKenna that he's sorry she got hurt and calls McKenna up to his desk and says that Josie can start tutoring sessions after school. In the end McKenna gets better grades and Toulane has a talk with her mom after the regional competition and is allowed to do Rhythmic Gymnastics, and Sierra takes Toulane's place on the team with McKenna.
