In a series of undercover investigations tracking some of the most popular foods we eat at home, Lawrence travels from farms and factories to packhouses and lorry depots across the world. She discovers why beef waste ends up in chicken, why a third of apples are thrown away, why all wines taste the same. She meets the hidden armies of migrant workers exploited throughout Britain on whom our supermarkets depend. And she shows how obesity, blighted town centres, environmentally ravaged fields in Europe and starving smallholders in Africa are all intricately related aspects of our newly globalized, industrialized system of 21st century food production.
