White Noise is a postmodernist novel written by Don DeLillo in the 1980's. It is told by the main character, Jack Gladney, a professor of Hitler studies at a school called "The College On The Hill". Jack and his wife have a terrible fear of death, but a new drug called Dylar may be able to help that. The major theme explored is the inherent fear of death that dwells within each and every one of us.
Set at a bucolic Midwestern college known only as The-College-on-the-Hill, White Noise follows a year in the life of Jack Gladney, a professor who has made his name by pioneering the field of Hitler studies (though he hasn't taken German lessons until this year). He has been married five times to four women and rears a brood of children and stepchildren (Heinrich, Denise, Steffie, Wilder) with his current wife, Babette. Jack and Babette are both extremely afraid of death; they frequently wonder which of them will be the first to die. The first part of White Noise , called "Waves and Radiation," is a chronicle of contemporary family life combined with academic satire.
There is little plot development in this first section, which mainly serves as an introduction to the characters and themes which will dominate the rest of the book. For instance, the mysterious deaths of men in "Mylex" (intended to suggest Mylar ) suits and the ashen, shaken survivors of a plane that went into free fall anticipate the catastrophe of the book's second part. Beyond the Gladney family, another important character introduced here is Murray Jay Siskind, also a college professor and friend of Gladney, who frequently discusses his theories, which relate to the rest of the book.
In the second part, "The Airborne Toxic Event," a chemical spill from a rail car releases a black noxious cloud over Jack's home region, prompting an evacuation. Frightened by his exposure to the toxin, Gladney is forced to confront his mortality. An organization called SIMUVAC (short for "simulated evacuation") is also introduced in Part Two, an indication of simulations replacing reality.
In part three of the book, "Dylarama," Gladney discovers that Babette has been cheating on him in order to gain access to a fictional drug called Dylar, an experimental treatment for the terror of death. The novel becomes a meditation on modern society's fear of death and its obsession with chemical cures as Gladney seeks to obtain his own black-market supply of Dylar. However, Dylar does not work for Babette, and it has many possible side effects, including losing the ability to "distinguish words from things, so that if someone said aloud the words "speeding bullet", I would fall to the floor to take cover."
Jack continues to obsess over death. During a discussion about mortality, Murray hypothesizes that killing someone could perhaps alleviate the fear. Jack decides to test Murray's theory by tracking down and planning to kill the man who had given Dylar to Babette in exchange for sex. After a black comedy scene of Jack driving and rehearsing, in his head, several ways in which their encounter might proceed, he successfully locates and shoots the drug-pusher, Willie Mink, who at the time is in a delirious state caused by his own Dylar addiction.
Jack puts the gun in Willie's hand to make the murder look like a suicide, but Willie then shoots Jack in the arm. Suddenly realizing the needless loss of life, Jack carries Willie to a hospital run by German nuns who do not believe in God or an afterlife. Having saved Willie, Jack returns home to watch his children sleep.
The final chapter describes Wilder, Jack's youngest child, riding a tricycle across the highway and miraculously surviving.
