The story takes place in a seaside inn called Jamaica, where a beautiful girl named Mary (played by Maureen O'Hara) travels a long way to visit her aunt, who is also the innkeeper, Percis (played by Marie Ney). On the way, Mary accepted the help of a man named Humphrey (played by Charles Laughton) and successfully arrived at the inn.What Mary didn't expect when playing was that Percy's inn had already become a haven for pirates, and Percy's husband Jess (played by Leslie Banks) was the pirate leader. Even worse, the seemingly kind-hearted Humphrey colluded with the pirates, and they fell in love with Mary's beauty and decided to take her away. Mary rescued a man named James (played by Robert Newton) from the pirates, and her action completely angered the cruel and ruthless pirates.
