During the summer of 1807, off the coast of Siam, a Royal Navy ship rescues a young castaway, Abel, who only remembers his first name. He soon becomes friends with the First Officer, who is standing in for the captain as the commander has apparently run away after stealing the treasures that were on board. Abel goes back to England aboard the Explorer, and he finds accomodation in an inn which is managed by the three daughters of the runaway captain. Abel will find out something truly creepy about himself before recovering his memory, and he'll realize the true nature of the ones who helped him.
