Captain Jim Marsden is wanted is about to be hanged for the murder of Voorhees, whom was owed money by Marsden after his ship was lost at sea with a million dollars in bullion. The murder was actually committed by Carter (Voorhees partner in criminal activities at Haunted Harbor) so he could control all the operations on the island. Yank and Tommy (two of Marsden's schooner mates) rescue Marsden from the gallows and the two set sail for Pulimati to escape the law, while operating Gallbraith's (friend of Marsden) trading post. The crew rescues Patricia Harding and her physician father during a tropical hurricane and they make their way to Pulimati. Marsden believes Carter is on the island, but does not know Carter runs a mining company under the name of Kane, and Dranga (assistant at the trading post) is in Kane's employ. Marsden is also having trouble getting the island natives to make supplies since they are afraid to go near Haunted Harbor, since Carter has his operations based there. Can Marsden free his name and, with the aid of Patricia, Yank, and Tommmy solve the mystery of Haunted Harbor? Very exciting serial with plenty of action you expect from Republic and then some. While it has the standard plot holes, implausible cliffhangers for any serial, the direction by Bennet (and Grissell who probably was in charge of dialogue) is great since often in the serial he leads the viewer to expect the unexpected in ways the chapter is playing out. Richmond, Aldridge (who is very gutsy here) and Barcroft make up a great serial cast and don't disappoint and Lewis, Geary, Duncan, Cooper round out the supporting cast. Great and fitting ending for our villain as well. Rating, 9.
