When we meet 27-year-old Rachel, an Orion spacecraft engineer in Denver, it is the morning of her procedure - one that may not work. No doctor has been able to help her. The main veins in her thighs and abdomen have been scarred shut for years, causing leg swelling that limits her activities. Since recently marrying her college sweetheart Greg, they have dreamt about having a baby…but her condition makes pregnancy too dangerous. Dr. Brooke Spencer takes on her case, the worst she has ever seen. Through pinholes, Dr. Spencer works to tunnel through the blocked veins to open them.
