U.S. Embassy employee Lee Cochrane and his wife, Sue, receive a shock when they discover that their 18-month-old son, Simon, has disappeared in London. He was last seen with their nanny, and the couple seemingly have no leads that might help police Detective Craig in his investigation. The media sensationalizes the incident, causing an unnecessary distraction as the couple prepares to confront the culprit face-to-face.
