On one fateful evening in 1939, WBN, a fourth radio network, is making its nationwide debut--and is engulfed in chaos. Penny Henderson, the station owner's secretary, has her hands full coping with a disgruntled sponsor, a tyrannical boss, an incompetent director, temperamental stars, unpaid writers on the verge of mutiny and, worst, of all, her soon-to-be ex-husband, Roger, who's determined to win Penny back. As the curtain rises on the opening act, a mysterious voice interrupts the program and menacing events begin to unfold--leading the WBN team to realize that dead air is the least of their worries!
