The highly anticipated pirate adventure, Black Sails, centers on the tales of Captain Flint and his men and takes place twenty years prior to Robert Louis Stevenson's classic "Treasure Island." Flint, the most brilliant and most feared pirate captain of his day, takes on a fast-talking young addition to his crew who goes by the name John Silver. Threatened with extinction on all sides, they fight for the survival of New Providence Island, the most notorious criminal haven of its day - a debauched paradise teeming with pirates, prostitutes, thieves and fortune seekers, a place defined by both its enlightened ideals and its stunning brutality.

Season two begins where we left off - The Walrus crew is stranded, with an army of Spanish soldiers standing between them and the precious Urca gold. And with their crimes against their brethren no longer a secret, Flint and Silver must join forces in a desperate bid for survival. Meanwhile, Eleanor Guthrie struggles to maintain her grip on Nassau, as a new breed of pirate arrives in the form of Ned Low, a man for whom violence isn't just a tool... it's a pastime. As blood is spilled, and tensions mount, Charles Vane must decide which he values more: Eleanor's life, or the respect of his men. And unbeknownst to all of them, a prize of immeasurable value has already been smuggled onto the island... one whose discovery will alter the very landscape of their world, and force everyone in Nassau toward the ultimate judgment: are they men, or are they monsters?

In the wake of the burning of Charles Town, all the New World lives in fear of Captain Flint. But when his campaign of terror crosses over into madness, it falls to John Silver to locate the man within the monster before it's too late. Meanwhile, with Eleanor Guthrie in prison, Jack Rackham oversees a new Nassau, hoping to secure his legacy as a king among thieves. All will be tested when a new threat arrives, one the pirates could never have anticipated. It knows them. It understands them. And in the blink of an eye, it will turn them against each other.
