For centuries the commons of England were lawful stopping places for gypsies and travellers. Today, an endless cycle of invasion and eviction brings frequent conflicts with the rest of society.

In this first episode, we meet mum-of-three Lisa Marie Whitcombe, who is entering two of her daughters into a beauty pageant, and Candi Donaldson, who has already taught six-year-old Frankie how to put on make-up and false nails.
The mothers also explain why they believed that by making their tots look their best, they are giving them the confidence to face the world.
