In 1980, John Wayne Gacy (William Forsythe of TV's BOARDWALK EMPIRE) was convicted of the rape and murder of 33 boys and young men – many of whom he buried beneath his suburban Chicago home. Thirteen years later, ambitious criminology student Jason Moss (Jesse Moss of TUCKER AND DALE VS. EVIL) began a bizarre correspondence with the serial killer by posing as a vulnerable gay teen. What followed was a nightmare journey into a world of violence, madness, and sexual depravity that brought home the true horror of Gacy’s crimes. Hailed by Maxim as a "true-life SILENCE OF THE LAMBS," the film is a chilling true story based on the best-seller that detailed an 18-year-old’s terrifying relationship with the most notorious mass murderer in American history.
