Eccentric inventor Caractacus Potts, his two children, and his beautiful lady friend, Truly Scrumptious, go on a picnic at the beach where they are soon whisked into a magical world of pirates, castles, and a flying car called Chitty Chitty Bang Bang. In the adventure that ensues, they journey to Vulgaria and encounter the evil tyrant Baron Bomburst and his child-hating wife, who kidnap Potts' children and steal Chitty Chitty Bang Bang. With the assistance of the kindly village toymaker, Potts plans an elaborate scheme to rescue the kidnapped children and Chitty Chitty Bang Bang from the Baron's castle on his birthday.
