Chronicling the partnership between a white surgeon and a black "technician" that led to a procedure to correct blue-baby syndrome in 1944. The principals: Vivien Thomas, a black man with a high-school diploma, and Alfred Blalock, the chief of surgery at Johns Hopkins. Blalock pioneered the surgery to correct the congenital heart defect while Thomas devised the procedures that were used. And they did it at a time, narrator Morgan Freeman says, when they "could not share the same lunch table."
