In 1717, the seas of the Caribbean are ruled by the Flying Gang: Black Sam Bellamy, Edward Thatch and Benjamin Hornigold. From their base in the Bahamas, these pirates steal a fortune from the wealthiest empires in Europe and disrupt the lucrative slave trade. English authorities tap Woodes Rogers to put a stop to the pirate attacks. He is on a mission to destroy the Flying Gang of the Caribbean.

There had been other pirate settlements in different places but none of them had worked quite the same way that Nassau did. There was a fort there. People stayed, they built a community on the land. Larger and larger numbers of pirate-minded people were showing up there and starting to develop an economy around themselves. Men like Edward Thatch, later known as Blackbeard, his sidekick, Black Caesar, a former slave, and the pied pirate that led them all there, Captain Benjamin Hornigold.
In the second episode, tensions rise between Benjamin Hornigold and Henry Jennings; their rivalry takes a new direction when Hornigold declares Nassau a pirate republic.

The pirates of the Caribbean's humble base in Nassau turns into a boomtown run by Benjamin Hornigold. But Hornigold's crew deposes him for his refusal to attack English ships; but one man, Edward Thatch, remains loyal. Meanwhile, pirate raids on British slaves provokes outrage.
