The Monkees rescue Princess Bettina, Duchess of Harmonica (Katherine Walsh) from her evil uncle Archduke Otto (Theodore Marcuse).

A band of gypsies, headed by the powerful Maria (Jeanne Arnold), force the Monkees to steal a priceless statuette called the "Maltese Vulture."

Peter is the target of a romantic prima ballerina (Ondine Vaughn) and a dastardly plot choreographed by the rest of the ballet company.
