When Treasure runs up a huge phone bill, she is only allowed one call a day. Then Brian comes up with the idea of setting up an e-mail account for her. Mum thinks its a great idea, but being someone of no understanding of new technology, Mum doesn't realise you have to pay to use the internet as well! Next Treasures' class go on a school trip to France. There's only one problem. Mum's going too!
