The Rock girls meet their new coach for the national team.

Coach MacIntire introduces a new training technique that pairs up each of the girls with a permanent training partner.

With only six weeks to go until the Olympics, Coach MacIntire is starting to feel the pressure as it appears his coaching style is not yielding the results everyone was expecting.

The girls are visited by their families, and Payson's dad gives her some bad news while Kaylie tries to curb her parents' feuding by making Austin tag along to a family dinner. Elsewhere, Lauren is advised to consult a doctor about her condition.

The girls compete in the semi-qualifications. Meanwhile, Kelly's mother tries to take down Kaylie; Payson gets overprotective about Lauren's health issues; and a new curfew halts Payson's burgeoning romance.

Lauren is heart-broken to discover that her heart condition will require surgery and wonders how this will affect her chances of making the Olympic team.

Lauren undergoes an experimental procedure, and her recovery time weighs heavily on her future as a possible Olympic gymnast. Elsewhere, Jordan's world is shaken by the arrival of an unexpected visitor.

In the series finale, Payson boldly changes her floor routine, jeopardizing her spot on the team. Meanwhile, Kaylie's shocked by her drug-screening results; Lauren weighs her recovery against her Olympic dreams; and Jordan won't accept help from Kaylie.
