From 1972 to 1978, 33 young men were kidnapped, murdered, and buried in a crawl space beneath their killer's house. And nobody knew about it for years. Why? He was charming, had a good job, was a community leader, and even volunteered to entertain sick kids while dressed as a clown.

This limited series peels back the twisted layers of John Wayne 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.
