Lorrie, Harriet and Sarah decide to include their 'singing' group in the school concert. Auditions are listed on the noticeboard on a day when Harriet and Sarah aren't at school so the responsibility for finding out their one and only time to audition is left to Lorrie.
But Lorrie is having eye trouble (she's sure she doesn't need glasses though) and she misreads the day. The girls are furious when they find they've missed their opportunity so Lorrie has to find a way to make amends. She finds another group who have yet to audition. They comprise a drummer and a guitarist and call themselves N Space. They obviously need the girls, but will the three of them blend well, and does this mean the end of Ratz?
