The series is set in the early 18th century, a time when piracy was rampant in the Caribbean. The story takes place several years before the events of "Treasure Island" and follows the adventures of Captain Flint and his crew as they sail the high seas, plundering ships and seeking revenge against their enemies. The show's creators drew inspiration from historical records and accounts of piracy during this era, ensuring that the series remained true to the spirit of the time.
