Oscar Mild is called upon by his home movie society to speak and show one of his films. He is so excited that he gets a bit nervous. His friend from outer space, Astronut, takes him to the drive-in to relax him. The theater is running a new science fiction picture, "They Came From Planet Mishagoss." When Oscar appears at the film convention, all he can think about is that movie. His talk is "mishagoss" this and "mishagoss" that. (The Yiddish word "mishagoss" can be variously defined as "insanity," "absurdity," "nonsense" or "a mess of trouble.")
