The Jolly Sailor is a pirate comedy drama for teenagers. It is based around a group of friends and among them is William who is not the adventurous type. You could say he had lead a sheltered life because that is how his father, a customs officer, had arranged it - if he had known that his mother was Gracie O'Donnell - the Pirate Queen - his life would have been very different.
On a trip to France William is kidnapped by the Cornish Captain Rumtug and his daughter Martha May, and traded as a commodity with a price on his head... He is delivered to a castle in Ireland - which to his astonishment is owned by grandparents he never knew he had. He hatches an audacious plan to kidnap Martha May. After twists and turns of the plot we arrive and the finale - and what a finale!
