Synopsis by Hal Erickson
Going undercover, reporters Clark Kent and Lois Lane investigate the murder of an elderly watchman from the Metropolis Munitions Factory. It turns out that factory owner Jones is the head of a gang of saboteurs, determined to commit various acts of mayhem before blowing up the plant. Stumbling onto the conspirators, Lois goes to great athletic lengths to avoid capture, but is ultimately bound and gagged and stuffed into a torpedo tube, which is then fired at a naval vessel. Looks like it's time for Clark Kent to assume his true identity as Superman and go into action--which he does, and how!
