We all know that before human beings were blasted up into space, it was the monkeys who were the only living creatures to orbit the globe from miles above. This animated tale sees a group chimps working for NASA sent into space on a routine mission: one is named Ham III, the grandson of the first chimp astronaut and not particularly well versed in the ways of space travel due to his upbringing in the circus. However, he becomes a reluctant hero when he and his crewmates decide to save the peaceful inhabitants of a distant planet from the evil dictator Zartog.
