Irishman Peter Blood and his crew of escaped slaves and political prisoners have taken their captured Spainish Galleon to the free port of Tortuga to elude both the Spainish and British Navies. But their ship is undermaned, and they soon realise that she is prised by other bigger and more ruthless pirate crews. Especially that commanded the notorius Captain Easterling. So, Captain Blood and his men set sail one night, hoping to make a Dutch port where they can resupply for a crossing back to Europe. But Captain Easterling and his bloodthursty crew of pirates are in hot pursuit.
