The Pogues are stranded in Morocco after JJ's death in Outer Banks Season 5.
Season 5 begins in the aftermath of the Season 4 finale, when JJ Maybank is killed by Chandler Groff. The Pogues are left mourning far from their home in Kildare County, and Morocco becomes the immediate setting for their grief, danger, and pursuit of revenge.
Morocco is also important to the wider production history of Outer Banks because the series previously filmed there for Season 4. That can lead to confusion between the fictional setting and the real filming locations used by the production. In the story, the country's role is tied to the Pogues' separation from home and the consequences of their search for the Blue Crown.
