In 1715, the notorious pirate Edward Teach - otherwise known as Blackbeard - reigns over a nation of outlaws and thieves on the Bahamian island of Santa Campana. It's a marauder's paradise unlike any other on Earth, and is quickly becoming a threat to international commerce.

Blackbeard has his diabolical mind set on obtaining the world's first longitude chronometer, which is said to have the ability to drastically alter society, sea trade, and business on a global scale.

He orchestrates an attack on an English vessel in an attempt to steal the device, but an undercover English spy named Lowe destroys it before it can fall into the wrong hands.

Blackbeard takes Lowe as a prisoner back to Santa Campana, where he is tasked with reassembling the chronometer. But while doing this, Lowe also must devise a way to foil Blackbeard's grand scheme.
