Nancy's going to the White House, where George is interning as a photographer's assistant. On the very day of Nancy's arrival, a critical photo-session is underway. The subject is a priceless gold statue of a hummingbird. But something is wrong with this picture. Just before the shoot begins, Nancy is knocked out cold. The bird, a gift to the United States from the country of San Valente, is gone, and soon after the statue disappears, so does the San Valente ambassador. From the White House to the Washington Monument to the Lincoln Memorial, Nancy sets out in hot pursuit of the kidnappers - and finds herself on a nonstop tour of danger!
