In the summer of 1982, five naked women are discovered in or near the Green River, strangled by their own clothing. Seattle area investigators launch a massive hunt for this voracious serial killer, chasing down bizarre leads and multiple suspects. As the victim count reaches forty, Ted Bundy provides shocking insights into the mind of this unprecedented killer.

The Green River Killer is murdering the most vulnerable girls near Seattle. But he leaves few clues behind. Detectives chase down several hot suspects, until a single DNA swab reveals the shocking truth. He’s Gary Ridgway, a happily married man with a secret obsession with prostitutes. What shocking childhood events drove this mild-mannered man to murder at least fifty women?

He was once a normal, happy child, but violent, drunken abuse from his father sends John Wayne Gacy down a dark and sinister path. Running from home, he takes a job at a mortuary where he first develops a fascination with dead bodies, even sleeping in a coffin with a corpse. Soon after, he’s married with two kids, but urges inside him can’t be contained. Convicted for sodomizing young boys, his normal life ends and the darkness takes over. Gacy begins cruising for young men leading to his first of many murders and the beginning of his crawlspace burial ground. He brings them home, then tortures, and kills them with what he calls “tricks.” Restraining boys and strangling them with rope, he fills the crawlspace under his home with bodies. His wife and many others suspect he’s up to no good, but thanks to his public persona, Pogo the Clown, no one realizes the depths of his evil. Then, one victim, Jeffery Rignall, is raped, tortured, and released by the serial killer. Unable to get help from police, Rignall goes on the hunt, staking out freeways until he finally discovers the monster’s home. Gacy may finally be brought to justice.

One of Gacy’s victims, Jeffery Rignall, has survived and tracked him down. Going to police, Rignall tries to bring Gacy to justice, but his polished public persona, including clown performances for young children, fools everyone. Gacy continues to kill and he’s run out of space under his home. Confident no one can catch him, Gacy begins dumping bodies in the Des Plaines river outside Chicago. Then, his arrogance gets him into serious trouble. Kidnapping a boy outside his place of work, he has no idea the boy’s mother is waiting inside. Detective Joe Kozenczak takes the case and discovers Gacy’s dark past of pedophilia. He finds an array of items linked to young boys, but the boy he’s searching for isn’t there. Kozenczak orders 24-hour surveillance while continuing to dig for details on Gacy. Then, he finds what he’s looking for, a photo receipt found in Gacy’s home was in the missing boy’s jacket when he disappeared. Under constant surveillance, Gacy lets police into his house where they smell the odor of a morgue. A second search of the home reveals the bodies buried underneath. The killer clown is found guilty of 33 counts of murder and sentenced to death.
