Synopsis:
Killer Shark kidnaps Professor Renault, the inventor of a magnet that can extract gold from sea water. The Blackhawks are unable to stop the kidnapping or prevent Killer Shark from escaping. To find his hidden underwater base, the Blackhawks coat their submarine with gold plating. When Killer Shark uses Renault's gold magnet, the submarine is attracted to it. The Blackhawks find the base, and Blackhawk floods it. The team rescues Renault and destroys the gold magnet, but Killer Shark gets away.
