Captain Silver of the Sea Hound tries to help a woman find her father, who disappeared on a distant island while hunting for treasure.
Given the choice between the Columbia serials that emphasize action and those that emphasize plot, I tend to opt for the latter. Fortunately for me, this is one of the latter. It's nice to see Buster Crabbe again; he really was the most memorable of the serial actors and always gave a matter-of-fact conviction to his performances. In terms of fantastic content, the serial itself is rather marginal; mainly, it involves some of the gadgets that were created by Captain Silver's oriental crewman named Kukai (pronounced "Cookie") to help defend the ship, including a bizarre gun that shoots fireballs.
