Voyage to the Bottom of the Sea: The Magnus Beam on AllMovie

A Middle Eastern country has acquired a mysterious ray weapon that successfully knocks down an American spy plane. Seaview is ordered to investigate, and Crane must make contact with the country's political underground. But the country's leader, General Gamal (Malachi Throne), is more devious and dangerous than his opponents guess -- Crane ends up being captured and used as bait for the Seaview, when the same weapon threatens to disable and crush the submarine.
