America has built the world's largest bomber plane and Japanese agents stow away intending to steal it. Lois hides as well, hoping for a better story and comes out of a locker to find the crew has been tied up. She radios for help but the Japanese drop a bomb preventing planes from taking off without a runway. Clark changes and heads up to save Lois from being tossed out the bomb chute. He overcomes the first two agents and the third panics and smashes the controls of the plane. He safely sets Lois back on the ground and then does the same with the plane.
