Portia is a reluctant princess, horrified by her father's idea of marrying her off to a boring prince. So rather than endure years of dull matrimony, she sells the family jewels, buys a ship and escapes to sea - with her ladies-in-waiting as crew. When Portia hear news that her favourite cousin is also being set up for an unsuitable marriage, she and her crew swing into action and set off to the rescue. Soon Portia's services are in high demand from indignant princesses worldwide.
