Seasons 1—4 of "Black Sails" submerge you in the barbarous world of pirates 20 years prior to the events of Robert Louis Stevenson's classic novel, Treasure Island. Captain Flint, the most brilliant and feared pirate of his day, joins crew member John Silver to fight for the survival of New Providence Island. Blood spills and tensions mount throughout "Black Sails" as new pirate breeds threaten and challenge the supremacy of Captain Flint in the Caribbean of the early 18th century.
