Plot Synopsis

DAHMER ON DAHMER: A SERIAL KILLER SPEAKS is a two-night, two-hour special that dives into the mind of America's most notorious serial killer, Jeffrey Dahmer. Twenty-five years ago, Milwaukee resident Jeffrey Dahmer was tried and convicted of 17 gruesome murders, shaking the public's perception of evil to its core. The shocking nature of his crimes -- luring young men into his home, where he drugged, sexually violated, killed and eventually consumed his victims -- unmasked a madman walking in the shadows and launched the question: how did a once mild-mannered, handsome young man become one of history's most terrifying and unexpected serial killers? During his time behind bars, one of the nation's leading investigative journalists, Nancy Glass, secured both exclusive access and the first televised interview with Dahmer, developing a candid relationship in which he divulged the darkest details of his life and crimes. With new revelations and never-before-seen interviews, this two-part documentary sheds light on the grizzly and complicated investigation through the eyes of pivotal figures in the case, including Nancy. Looking back on her first interview with Dahmer, Nancy highlights on-and-off-camera conversations detailing Dahmer's disturbing crimes through his own words, giving insight into his dark, depraved manner and reasons for killing. This two-parter also features Dahmer's parents, Lionel and Shari, who haven't spoken about this case or their son publicly in over 20 years; and surviving victims Billy Capshaw and Preston Davis, who have decided to finally break their silence about what happened to them. Their unique experiences with Dahmer throughout various stages of his life expose a serial killer unlike any other -- one not motivated by the impulse to kill, but rather the desire to exercise control. DAHMER ON DAHMER premiered as a two-night event on Saturday, November 11 and Sunday, November 12, 2017 at 7pm ET/PT on Oxygen, with encore presentations at 9pm each night.
