This three-part miniseries steps inside the ground-breaking medical frontier of fetal surgery with an intimate look at The Special Delivery Unit at The Children's Hospital of Philadelphia, where a courageous group of doctors and their patients take on the challenges of operations done on babies still inside their mother's wombs. With exclusive access to this elite unit, the film captures rarely-seen, real-time footage of fetal operations. Meet expecting parents as they face gut-wrenching decisions: should they take a leap of faith to repair birth defects with prenatal surgery, even if it means they might lose their child? And, hear first hand from the unusual team of doctors who have defied skeptics and chosen to pursue this high-risk, high-reward career path.
