Olivia and her little sister, Angeline, have had an unusal sort of life. Living with their eccentric mum in a variety of B & Bs and council flats, they're used to moving around a bit - but nothing could have prepared them for Mum's latest hairbrained scheme: going to live in a Department Store! But Mum is determined, sneaking them in just as the doors are closing and hiding them under one of the display beds, she's very confident that her plan will work - who's going to know? All they have to do is be very very quiet and very very careful. Olivia is not so confident - there's just so many leftover cafeteria meals you can eat - and even 500 TVs on all at once can lose its appeal after a while. Olivia is certain this is going to end in disaster - how on earth are they going to get awy with it? Eventually the inevitable happens, but not, reflects Olivia, before she, Mum and little Angeline, have had the time of their lives!
