Living incognito in River Heights, Madame Alexandra seeks Nancy's help in finding her missing grandson. Armed with only a faded photograph of the prince at the age of four, Nancy embarks on a perilous search, with her friends Bess, George, Burt, Dave, and her special friend, Ned, always by her side.
