The Rock's Athletes compete for places on the club's team for nationals. Emily ranks third ahead of Lauren, despite Lauren's attempt to sabotage her vault.
The girls' futures are thrown into turmoil when their head coach, Marty Walsh Erik Palladino , is blackmailed out of his job at The Rock by Lauren's father Steve, who is angry that his daughter was beaten by Emily.
Marty is forced to move to The Rock's rival gym in Denver, taking Lauren and other gymnasts with him.
