Whilst showing off her dangerous hover-bike skills without wearing her helmet, Una is almost fatally injured and is confined to a hover chair. Unable to come to terms with her new situation, she also has to learn to deal with the taunts and intolerance from snide rival Layla. Miserable and feeling alone, she turns to the only person she thinks can help her - her dad. Through determination and hard-work, Una gets herself out of her depression and enters the championship hyperball challenge, much to the horror of Layla.
