When Tilly Trolley has a fall on the shopping centre escalator, Brandie and Boyle Barrier offer to help. When they arrive in the back corridors of the shopping centre however, they uncover a warehouse packed full of boxes of crisps and snacks. What started out as a favour from Bennie and Beatrice Barrier's parents quickly turns into a reunion with those that Brandie and Boyle left behind in the crisp factory in Leicester when they were recycled into barriers and moved south. Unfortunately though, not everyone is happy to see them.
