The plot centers around a crew of three on board a spaceship which scouts asteroid fields for new materials which can be mined.
Led by Crispin Eller, the crew (which consists of second in command Blake and Silvia) land on an asteroid and send a pack of hamsters in order to check the radiation levels.
Pondering over the changes, the crew realizes that the radiation has vastly increased their evolution, and that they've evolved millions of years in a matter of days.
Blake insists on going back to Earth so they can assume control with their powerful minds, while Eller is more cautious.
It is revealed that the orbs of energy are actually the hamsters which have received the radiation first, and have evolved millions of years and are now nothing but pure energy.The beings then revive Silvia and undo their evolution before leaving.
