After success at the Scottish Championships, acrobatic pair Finn and Kirsten have their sights firmly set on selection for Acro World Championships, but for this they need a medal-winning routine. So coach Nikki has brought in top choreographer Andrew Griffiths - the man behind Britain's Got Talent winners, Spellbound, who hopefully holds the key to success. Meanwhile, things aren't going so well for acrobatic duo and best friends Dove and Izzy and coach Nikki thinks she knows why. It's time for a talk with the girls when they'll need to make some difficult decisions about their future partnership.
