t's the halfway point at Solar Blue and all the kids are on track for qualifying for the end of year surf-off. Angus arrives with the prototype of a new surfboard. Solar Blue needs to make a commercial contribution to the parent company, Matsusito, and Angus wants the kids to promote the new board. They're told that they must use it in the next comp, but their first practice session is a disaster. Not only is the board too light, it's seriously unstable and they all have trouble just staying upright. But with the CEO of Matsusito coming to watch the competition, Angus is adamant that they must persist with the new boards - and win! With the future of the Academy at stake, the kids feel that they have no choice but to try and make the best of it. After a disastrous first round, Cassie decides that promoting a product that is no good, just isn't worth it. She convinces the rest of the kids to use their own boards; if this is their last surf for Solar Blue, then they may as well look good! With a renewed sense of conviction, the team blow the competition out of the water. But will Matsusito allow the Academy to remain open?
