As Chapter four of Radar Men From the Moon reveals, Commando Cody (George Wallace) managed to leap from his car before the bridge exploded. Meanwhile, Krog (Peter Brocco), Retik's emissary on Earth, is swiftly running out of money and when a bank robbery turns sour he convinces Graber (Clayton Moore) to kidnap Commando Cody for ransom. Cody, alas, is not available so Graber takes off instead with poor Joan Gilbert (Aline Towne). Using his rocket suit, Cody is able to catch up with Graber's aircraft and the latter bails out after disabling the controls. As chapter four reaches its conclusion, the plane carrying Cody and Joan crashes into a mountainside.
