New York City, 1929. A sanatorium, a deadly disease, and a dire nurse shortage.

So begins the remarkable true story of the Black nurses who helped cure tuberculosis, one of the world's deadliest plagues, told alongside the often strange chronicle of the cure's discovery.

During those dark pre-antibiotic days, when tuberculosis killed 1 in 7 people, white nurses at Sea View, New York's largest municipal hospital, began quitting. Desperate to avert a public health crisis, city officials summoned Black southern nurses, luring them with promises of good pay, a career, and an escape from the strictures of Jim Crow. But after arriving, they found themselves on an isolated hilltop in the remote borough of Staten Island, yet again confronting racism and consigned to a woefully understaffed facility, dubbed 'the pest house' where 'no one left alive'.

Spanning the Great Depression and moving through World War II and beyond, this story follows the intrepid young women, the 'Black Angels', who, for twenty years, risked their lives working under dreadful conditions while caring for the city's poorest - 1,800 souls languishing in wards, waiting to die or become 'guinea pigs' for experimental (often deadly) drugs. Yet despite their major role in desegregating the NYC hospital system - and vital work in the race for the cure for tuberculosis and subsequently helping to find it at Sea View - these nurses were completely erased from history. The Black Angels recovers the voices of these extraordinary women and puts them at the centre of this riveting story celebrating their legacy and spirit of survival.
