In 1619, a pirate cutter, the Sea Devil, captured a Spanish cargo ship called Santa Susanna. Before reaching its destination the Sea Devil was caught in a storm and wrecked on the uncharted Cutthroat Island. Only one member of the crew managed to get off of the island alive, Fingers Adams. Before dying he made a map and tore it into three pieces which he gave to his legitimate heirs. In year 1688, as the pirate Morgan Adams who currently has one piece of the map, the player has begun a quest for the other pieces of the map in hopes of eventually finding the treasure. Already a wanted woman, Morgan will need to fight the law as well as those who hold the pieces of the map.
