The heroes of our film live on an idyllic, little planet in a neighboring solar system. Egon is an ever so slightly eccentric, amateur ‘rocket scientist’ assisted in his endeavors by a clumsy, and decidedly overfed, catlike creature called Donci. Their simple existence becomes suddenly complicated when an unidentified object flies into their lives with a message from Earth. Egon decides that there is only one thing to do and that is to establish contact with this distant civilization.
