Synopsis by Hans J. Wollstein
A Universal serial in ten chapters, Haunted Island was a remake of the studio's earlier The Brass Bullet (1918). Jack Daughterty starred as Jerry Fitzjames, a young man who comes to the aid of lovely but beleaguered Rosalind Joy (Helen Foster). The girl has inherited the ill-named Pleasure Island, a haunted atoll complete with a buried treasure also desired by an evil uncle (Al Ferguson). The uncle and his henchmen do their level best to separate the girl from her inheritance. In the end, however, Rosalind's birthright is saved not so much by the chivalrous Jerry but by a mystery hero known only as "The Phantom Rider."
