Invisible Monsters: Serial Killers in America

Weaving together the stories of five of America's most notorious serial killers - Ted Bundy, John Wayne Gacy, Jeffrey Dahmer, the Green River Killer and BTK.

In the mid-to-late 1970s, Bundy, Gacy and BTK begin claiming victims, while Dahmer and the Green River Killer inch ever closer to realizing their grim fantasies.

With their confidences growing in 1978, Bundy, Gacy, Dahmer, the Green River Killer, and BTK - also known as "The Five" - continue their game of cat and mouse with law enforcement.

In the mid-1980s, two of "The Five," Gacy and Bundy, sit on death row as their murderous rampages have at last been curtailed.

After years of public fear at the hands of "The Five," the remaining three killers are captured between 1991-2005.
