Eddie O’Gorman, the chair of Spanish Armada Ireland, hopes the film will entice visitors to Streedagh beach, which overlooks sunken wrecks.
The film was made by Spanish Armada Ireland, a voluntary group based in Sligo that used €100,000 (£90,100) of community development funding to recruit an international cast and crew and make a swashbuckling half-hour film.
Streedagh beach was the setting for young love in the TV drama Normal People, but its latest screen depiction reveals a dark history of plunder and slaughter on the golden sand.
Instead of romance among the dunes, viewers encounter drownings, stabbings and hangings on this bucolic stretch of Ireland’s Atlantic coast.
