Eight young Rwandan children set out on a perilous journey, leaving their families in search of critical heart surgery in Sudan. Their hearts, damaged by a curable illness stemming from childhood strep throat, leave them with only a few months to live. “Open Heart” uncovers the interconnected efforts of Dr. Emmanuel, Rwanda’s sole government cardiologist striving to rescue his young patients, and Dr. Gino, the chief surgeon at the Salam Center, who is battling to preserve his hospital, the sole provider of free, life-saving cardiac surgery in Africa for the millions in need.
