Description:
The aliens are invading! No, they're not from another galaxy. They're not even from Mars. They're from Hollywood! A science fiction convention has come to Bayport, and movie director Simon Devoreaux has lost his billion-dollar baby: the film of his latest blockbuster has dematerialized before his eyes.
