In 2018 Rhonda Rowland traveled from the United States to England to meet the doctor who discovered the drug that saved her life. Wilson disease was a fatal disease until Dr. John Walshe discovered penicillamine in 1955. However, the drug didn't work for everyone so he developed a second medication known as trientine. Rhonda also talks with Dr. Walsh's first patient, Shirley Wiley, who was going strong at 79-years-old. Dr. Wilson's son tells Rhonda that his famous father didn't know what caused the disease that's named after him, though he knew it runs in families and suspected a toxin was involved. It was later discovered that WD is a liver disease involving copper metabolism.
