A new girl, Emily Kmetko, comes to train with they veterans at the gym and finds that they are both impressed and threatened by her.

The exit of Coach Marty and one of "The Rock's" top guns, Lauren, causes chaos at the gym. Prompting Payson, Kaylie and Emily (with Becca in tow) to head for Denver with a plan to confront them about their defection. All of this happens at the same time as the Cruz's (Ronnie and Alex) invite everyone to the mansion for a meeting. Meanwhile, Lauren is less than pleased at the cool greeting she receives at the new gym. And shocked by the discovery that she makes concerning her father and his 'Personal Assistant', Summer.

After busting them for going to the party, Sasha puts the girls through a rigorous day of training and team building.

Taking a gamble that the girls are ready and can use the motivation for Nationals, Sasha invites Marty and the Denver team to The Rock for an invitational meet. Payson is determined to show that she is the best, but when an old injury flares up, it might have devastating results. Emily is also resolved to show what she can do, but Sasha has other, less advanced plans for her. But with reigning Nationals champion Kelly Parker (guest star Nicole Anderson, “JONAS”) in tow, are the girls really ready for the Denver gym and this challenge?

Meanwhile, Carter has to rethink his relationship with Kaylie when Sasha and Lauren give him an ultimatum.

The Rock is gearing up for Nationals, and with that comes more pressure, while Emily has to deal with the consequences of her actions.

Kaylie faces the challenges of being a national champion; Payson tries to come to terms with her injury.

The girls devise a plan to get Marty fired; Sasha attempts to find a place for Payson at the gym.

After going rogue and defeating the Chinese National Team but going against the NGO, the The Rock girls are at their best. But when they find out the National Team is having team practices without them before an Invitational meet in France, the girls are not that confident that they will make the cut. And now Payson is back and she is determined to get to the top once again, but is she really ready? And Carter and Lauren's relationship is starting to heat up, but when will they let Kaylie know about it?

When the men's Olympic champion, Austin Tucker, begins temporarily training at The Rock, egos clash when he tries to move the girls' equipment. To settle the matter between the male and female athletes, Sasha decides the two must compete for gym space, but there's a catch – the girls must perform on the men's apparatuses and vice versa. With Payson unsure about her future in the gymnastics world, Kaylie, Emily and Lauren are forced to face the men on their own. Will they be able to beat the boys and have the gym they made famous remain theirs? And will Payson choose to fight for her dream, or forever leave the sport that destroyed her?

The Rock gears up for the annual awards banquet dinner, The Rocky Awards, and Lauren is determined to win the Miss Congeniality award the best way she knows how – with bribery and cheating. But even after all the free smoothies, barrettes and massages, will Lauren get her way or will she be usurped by a silent but strong contender – Emily?
