In Singapore, two Marine Lieutenants, Tom Grayson and Frank Corby, uncover the threat of a masked terrorist called The Lightning, who uses an arsenal of powerful lightning-based weaponry in his bid for world conquest. These electrical fireballs are similar to the Foo Fighters that appeared during WWII. The battle becomes personal when The Lightning annihilates the officers’ unit and later kills Lt. Grayson’s father as he was helping the investigation of the weapon. Now, the marines have dedicated themselves to stopping The Lightning and bringing him to justice… This movie is famous for its main villain, The Lightning—the very first costumed supervillain. There is some speculation that George Lucas used The Lightning as a template for Darth Vader. Starring Lee Powell, Bruce Bennett, and Eleanor Stewart. A great action serial!
