One of the world's most shocking medical cases lies hidden in a remote region of Viet Nam. 31-year-old Hai Nguyen has not left his bed for six years, weighed down by what is, quite possibly, the largest tumor in the world. Hai suffers from neurofibromatosis, a genetic disorder that causes tumors to grow on nerves in the body. Hai's tumor now weighs two hundred pounds. It is stealing so much blood, doctors have given Hai less than a year to live. Vietnam's medical community does not have the experience to remove large tumors. But when Hai's case comes to the attention of renowned plastic surgeon, Dr. McKay McKinnon, the American surgeon journeys to Ho Chi Minh City to undertake the most difficult surgery of his career. Can a worldwide effort save the life of this extraordinary man?
