A family vacationing in the mountains near Crystal Cove is attacked by a polite Englishman in a mask calling himself the Dandy Highwayman, who blows up the family’s station wagon and leaves with the mother. Later, the gang stumbles upon the wreckage of several cars on the mountain roads and decides to investigate. As they investigate, the Highwayman kidnaps several women from around Crystal Cove, including Mayor Nettles, Daphne, and Mrs. Blake, and steals all of the money from the Blake safe. With inside help from Daphne (who is safe and sound in the Highwayman’s lair), the gang traps the Highwayman, revealed to be a lonely librarian who wanted to have a more exciting and adventurous life.
