Four privileged young ladies swap the leafy lanes of the Home Counties for the streets of south London to experience for themselves how life is lived on the other side of the tracks. Stephanie, Serena, Claire and Cat are posh and pampered with virtually no experience of life at the other end of the social spectrum. All they know about Peckham is what they've seen on the news - shootings, stabbings and gang-related violence. Though curious they are understandably nervous. The girls move onto a local council estate and immerse themselves in an alien and unfamiliar world - Peckham's vibrant, multi-ethnic community. Attitudes are further tested when they meet the four local women who have volunteered to act as their personal guides for the week - streetwise Kerri, unemployed Sarah, single mum Lashan and hard-working Aleisha. Bridging the class divide proves tricky, and relations between the posh girls and their Peckham 'sisters' quickly sour. Can the two sides overcome their differences and make it through the rest of the week?
