To save a little girl abducted by aliens, Superman will have to make one of his most serious decisions: to stay with his own people and continue to protect them, or to go through the universe in search of him and let Metropolis and Earth abandon. With an optimism and a sense of infallible duty, the Steel Man does not procrastinate long before he flies... up into the sky.
