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 trades his guitar for a con man’s treasure map. On a deserted island, the Monkees go hunting for treasure—and are hunted by a mad Australian (Monte Landis) and his man Thursday (Rupert Crosse).

The Monkees take a vacation from the studio grind and are chased (on location) all over the French Capital by beautiful girls and gendarme.

The Monkees swing to the rescue when mentalist Oracullo (Monte Landis) gains control of Peter's mind to use him in a nightclub act. Director James Frawley appears as Oracullo's assistant Rudy.
