In a delightful twist of fate, the youthful Frederic was supposed to be trained by a pilot but ended up under the care of Ruth, a well-intentioned nursemaid whose hearing difficulties led her to mistakenly assign him to the care of the Pirate King. Now on the brink of adulthood, Frederic faces a significant dilemma: his period of service is over, and he must choose whether to leave his life of piracy behind or embrace a future filled with thrilling swashbuckling adventures. Meanwhile, Ruth’s heartfelt pleas for companionship seem to fall upon deaf ears as Frederic finds himself captivated by the enchanting Mabel, one of Major-General Stanley's lovely daughters.
As destiny would have it, Mabel agrees to help Frederic escape the life of piracy by promising to marry him. Nevertheless, their joy is short-lived when the pirates return, abducting the young maidens with the intention of marrying them off to their fellow rogues. In a clever feint, Major-General Stanley fabricates a story about his past, claiming he is an orphan to protect his daughters from the pirates' grasp. True to their code, the pirates release the General and his daughters, respecting this deceptive plea.
However, guilt starts to weigh heavily on the General’s conscience, prompting Frederic and Mabel to console him. In an effort to resolve the situation, Frederic seeks assistance from the local constabulary, yet the authorities prove ineffective against the fierce marauders. In a surprising revelation, Ruth announces her findings regarding the intricacies of Frederic’s apprenticeship contract, highlighting that he is still tied to the pirates because of his birthdate—February 29th—which won't allow for his release until he turns 21 in the year 1940.
Determined, Mabel vows to wait for Frederic, while the Pirate King and Ruth scheme their next steps. As the pirates make their approach, the constabulary arrives seeking refuge. A confrontation ensues when the pirates face the authorities. Although vastly outnumbered, the pirates ultimately relent when the Sergeant of Police commands them to surrender in the name of Queen Victoria.
Touched by their devotion to their sovereign, the pirates surrender with tears, freeing Major-General Stanley in the process. In an unexpected twist, Ruth discloses that these pirates are actually noblemen who have strayed from their honorable paths. With a heart full of compassion, the General pardons them and invites them to restore their former dignity as parliamentarians and wed his beautiful daughters. As everything unfolds, Frederic and Mabel find themselves joyously reunited, embraced by a tapestry of vibrant characters, all discovering love and redemption in this enchanting saga of a pirate's life.
