Following last season's 18-month flash-forward showing Wes Genrette's proposal for the Pogues to find Blackbeard's treasure, Season 4 takes us back in time to the lead-up of that moment. After finding the gold at El Dorado, the Pogues return to the OBX and commit to having a "normal" life. They've built themselves a new safe haven, officially dubbed "Poguelandia 2.0", where they live together and run a fairly successful bait, tackle, and charter tour shop. But after some financial setbacks, John B, Sarah, Kiara, JJ, Pope, and Cleo take Wes up on his offer, drawn back into the "G" game for a whole new adventure. But before they know it, they're well in over their heads, with dangerous new enemies hot on their heels racing them to the treasure. Meanwhile, their problems are only growing, and they're forced to question their past, present, and future - who they really are, has it all been worth it, and how much are they willing to risk?

After losing the gold and fleeing the Outer Banks, Season 3 finds the Pogues washed ashore on a desert island that, for a brief moment, seems like an idyllic home. Officially deemed "Poguelandia", the island's newest residents spend their days fishing, swimming, and reveling in the carefree lifestyle of their temporary dwelling. But things quickly go south for John B, Sarah, Kiara, Pope, JJ, and Cleo when they find themselves once again caught up in a race for the treasure, quite literally running for their lives. They're broke and far from home, they can't trust anyone, Ward and Rafe are hungry for revenge, and there's a ruthless Caribbean Don who will stop at nothing to find the bounty. Was the treasure ever within their reach? Or was it all a trap to stop them once and for all? Either way, it's the Pogues against the world - and the only way out is together.
