It's 1939, and Chicago radio station WBN celebrates its debut broadcast in this zany farce from producer George Lucas. While staff writer Roger Henderson (Brian Benben) tries to reconcile with Penny (Mary Stuart Masterson), his estranged wife and the de facto station manager, somebody is bumping off network employees. When Roger becomes the chief suspect, he frantically attempts to clear his name just as his unfinished program is about to air.
