Kaylie is put in rehab for her eating disorder and makes a new friend, Maeve, a model who has been in and out of rehab before. Sasha decides to leave The Rock and move back to Romania. Emily is told that under her probation that she is under house arrest and must wear an ankle monitor.

After being made co-captains, Lauren and Payson are at each other's throats. Steve finds the altered video of Payson and Sasha's kiss and confronts Lauren about it. Emily finally discovers that Chloe's new job is at a strip club.

The Rock girls prepare for a meet with the Pinewood Club, the worst-ranked gym club in the country. The girls worry that the Pinewood Club won't give them enough of a competition to prepare them for an up-coming international meet in Hungary. Meanwhile, Damon and Kaylie become closer as he starts recording his album at the recording studio in Kaylie's house.

Kaylie finally returns to training at The Rock, but the public is under the impression that her time away from the gym was from an ACL injury, not rehab for anorexia. Soon after, Sasha announces that Kelly Parker is going to replace Emily on the World team, and that Kaylie will be replaced, as well, since she has not had enough time to train.

Kelly Parker's manager, Shelia, arrives at the gym and starts scheming to make Kelly the most recognizable girl on the team, which includes trying to get Kelly to sabotage Kaylie by exposing her anorexia to the public. Meanwhile, Payson and Max come across a stray puppy while out jogging, and as they try to keep the puppy hidden until they can find it a home, Lauren becomes jealous of the amount of time they're spending together.

Shelia continues her quest to ruin Kaylie, which now involves taking away Kaylie's new endorsement deal with Healthy Bar. However, after hearing Kaylie give an interview about how Kelly should be the team captain because of her experience and accomplishments, Kelly starts to feel differently about their rivalry. At the same time, Kim and Summer start to put the pieces together about the true origins of the Payson/Sasha kiss video.
