Synopsis:
A man calling himself the Mole uses a powerful digging machine to tunnel through the Earth. He kidnaps several miners, leading Blackhawk to believe that the criminal wants men who can withstand tremendous pressures. He sets a trap for the Mole which leads the Blackhawks to the criminal's hideout. However, the Blackhawks are captured.

The team is put to work as slaves aboard a digging machine. The Mole intends to burrow under Fort Knox and steal the gold stored inside. Blackhawk feigns weakness under the tremendous underground pressures. His ruse allows him to plant a magnet on the digging machine's navigation controls. When the Mole surfaces, he finds himself in prison instead of Fort Knox.
