Starz released the teaser trailer for the fourth season of the Emmy®-winning Original series “Black Sails” that will bring fans to the heroic conclusion of the Treasure Island prequel. The 10-episode fourth season of the stand-out high seas drama returns in 2017, and finds our pirates at war in the West Indies. The shores of New Providence Island have never been bloodier, but the closer civilization comes to defeat, the more desperately, and destructively, it will fight back.
