Devil in Disguise: John Wayne Gacy: Story, Cast and Series Facts

Story and premise

From 1972-1978, thirty-three young men were kidnapped, murdered, and buried in a crawl space beneath their killer's house. And no one was the wiser. Not for all those years. Why? He was charming and funny. Had a good, All-American job. Was a community leader. He even volunteered to entertain sick kids... while dressed as a clown. Devil In Disguise: John Wayne Gacy peels back the twisted layers of Gacy's life while weaving in heartrending stories of his victims; exploring the grief, guilt, and trauma of their families and friends; and exposing the systemic failures, missed opportunities, and societal prejudices that fueled his reign of terror.
