In the 1940s, in an environment marked by racial segregation and prejudice, a talented cardiovascular surgeon, Dr. Alfred Blalock, and his African American assistant, Vivien Thomas, challenge the conventions of their time. Despite the lack of recognition and opportunities for Thomas due to his skin color, his ingenuity and skill are undeniable. Together they form an unlikely team at Johns Hopkins Hospital, where they work tirelessly on research and the development of innovative surgical techniques.
