The historian David Olusoga fronts this documentary exploring the rich history of immigrants coming to Britain to work in the NHS. Olusoga hears from patients, experts and a range of migrant medics, who talk about the challenges they have faced in an increasingly hostile environment towards immigrants. The story of Yvette Phillips – who has had two kidney transplants 34 years apart, the first performed by Sri Lankan surgeon Ossie Fernando and the second by his son Bimbi – exemplifies the international makeup of the health service.
