Synopsis:
A race of aliens arrive on Earth and imprison Superman in a force bubble. Superman and the military are unable to break the barrier. The aliens demand a thousand pounds of Kryptonite in exchange for Superman's release.

Jimmy helps gather the Kryptonite to free Superman. He not only gathers the thousand pounds requested, he gets fifty tons. The aliens release Superman, who falls to his apparent death when exposed to the Kryptonite. The aliens then land and proceed with their invasion.

However, Superman is not dead, the overdose of Kryptonite does not harm him at all. He apprehends the aliens and thwarts the invasion. Jimmy deduced that a large enough quantity of Kryptonite would not effect Superman, just as a large electric current does not kill a human being.
