Alex is off on holiday to Wonderland Holiday Camp and it's going to be brilliant! Her best friend Rosie is coming along and they're both going to be in the Kool Kids Club - free of boring parents and also free from Alex's mischievous younger brother, Evan!
Every night Kool Kids put on a show for the rest of the camp and Alex decides that this is her chance of the stardom she is so obviously destined for - her talents are sure to be spotted by a big talent scout! Tragically Alex's sworn enemy, Pearl Barconi (aka Macaroni!) gets the part and Alex's dreams of being discovered begin to fade. But when Pearl has a slight accident with a bottle of her mum's tanning cream and has to drop out of the play, it looks like Alex might just get that star role after all!
