'I keep trying to find something a bit exotic in my family tree. Best I could do was a great-grandma who looks a bit tanned in the old photos.' US election night 2008. A smart inner-London 'village'. For white ex-lawyer Natasha, adoptive mother to two Ethiopian children, tonight is the ideal opportunity to get to know the small handful of other 'mothers of children of colour' at their smart private school. But as the Obamatinis start to flow, the middle-class veneer begins to crack and Natasha's carefully planned social occasion quickly unravels. Lifting the lid on a stew of racial tensions and social embarrassments, this is a hilarious, provocative and brilliantly insightful look at the new 'Beige Britain'.
