For those who don't know the name and legacy of John Wayne Gacy, the movie is based on the true story of one of the nation's most prolific serial killers (33 murder convictions). Gacy depicts the methods upstanding citizen and neighborhood party clown Gacy (Mark Holton) used to seduce young men, slaughter them and then hide their bodies in the crawl space under the house he shared with his wife (Joleen Lutz) and children. ~ Buzz McClain, Rovi
