Pearl moves into 10 Downing Street when her mum Patrice becomes the UK's first Black female Prime Minister. A chance meeting with Patrice's childhood sweetheart Jackson and suddenly Pearl's glam new life has an unexpected gatecrasher: Jackson's daughter Izzy. 

Pearl and Izzy loathe each other on sight and have only one thing in common: a desire to split their parents up. 

But as Patrice's popularity in the polls begins to decline as a result of the girls' out- of-control sabotaging, will they realise that they are stronger as team?
