After a sign from God, Jennie and her friends decide to enter the upcoming 'Let's Get It On' dance battle which has a first prize of $10 000. After initial rehearsals it appears that their dance abilities aren't nearly as good as their mathematical prowess so Jennie hunts around the school for people with 'mega mad dance skills' to join their squad so that they may have a hope of beating the school skanks: Tracy, Tizzneen and Tessa. Simultaneously Cassandra is sacked from her position as a professional carer due to her negligence but then discovers that one of her charges, Marilyn, has won a colouring-in competition and that Cassandra will need Marilyn's help if she's to collect the prize for herself. Additionally it is revealed that Nigella's mother has been poisoning her which is the cause of all her strange allergies and illnesses.
