Famed German filmmaker E. A. Dupont, who in his peak years was responsible for such classics as Variety, merely goes through the motions in this updated sequel to Robert Louis Stevenson's Treasure Island. Instead of Jim Hawkins, the film offers Jim's beautiful female descendant Jamesina (Dawn Addams), who manages to get her hands on Captain Flint's fabled treasure map. This makes Jamesina the target of a variety of scurrilous fortune-hunters, including phony archeologist Harris (Porter Hall) and the malevolent, sightless Newman (James Seay). It is handsome archeological student Clive Stone (Tab Hunter) who helps Jamesina locate the treasure and elude the villains. At least Return to Treasure Island wasn't intended to be taken seriously.
