Having been apprenticed by mistake at the age of eight to a roving band of mild-mannered pirates, Frederic has at last entered his twenty-first year and is free to go. Alas, his sense of moral duty insists he vanquish his poor plundering friends. Hurt to see Frederic depart and even more desperate to thwart his plans to shut down their harmless pirating, the Pirate King discovers a curious paradox that will keep Frederic legally indentured for another 60 years. Meanwhile, Frederic has fallen in love with the first young woman he's ever seen -- the flower Mabel -- and enlists the help of her blustery father to keep the lusty priates at bay until the police can arrive. A rollicking, swashbuckling adventure in free-for-all hilarity and dippy delight.
