Artistic gymnasts Amelie and Phoebe have been busy preparing for the World Championship Team Trials, but Amelie is hit with a major setback when she injures her ankle in training. Phoebe is still determined to make it through to the selection and while she’s at full fitness, she doesn’t know if Amelie will be even be able to attend. Against all the odds, both girls make it to the trials, but the competition is fierce as they are up against the strongest senior female gymnasts in Britain. Will the girls make Coach Liz proud as they compete together as seniors with new routines and back from recent injury? Meanwhile, back at the gym, the tumblers have been set a back-flipping challenge – will our Gym Stars continue their winning streak or be beaten by Nile and his training partner, Luke?
