Superman / The Mechanical Monsters

S1, E1: When the Daily Planet receives a letter from a mad scientist who threatens to turn his ray gun on Metropolis at midnight, Lois flies a plane to the scientist's mountain-top lair to get the scoop--but is taken hostage. Superman must save the Daily Planet from collapsing after the building is targeted by the ray, but he proves that not even this city-destroying ray is a match for the Man of Steel as he nabs the scientist and rescues Lois. A band of giant flying robots has been robbing buildings in Metropolis, Lois and Clark guess the next heist will be from a jewelry exhibit. At the exhibit, when one of the robots steals the jewels, Lois climbs into a cavity with the stolen gems inside the robot, which flies away with her inside. Using his X-ray vision to locate Lois, Superman wrestles with the robot in mid-air, but the robot escapes. Now, will Superman reach the robot master's lair before Lois is lowered into a vat of molten metal?
