To Catch a Killer

In December 1978, Detective Joe "Polock" Kozenczak (Michael Riley) starts looking for a missing teenager and keeps arriving at the same name, John Wayne Gacy (Brian Dennehy). Gacy is a contractor, a neighbor who helps out, a man who dresses as a clown for children's parties. Eric Till follows ten days of the hunt, and Kozenczak has to build a case against a man everyone around him likes.
