Using exclusive interviews and spanning half a decade, the Cheshire Murders reveals the shocking police failures and untold personal dramas behind the notorious rape-arson-homicide case that shook Cheshire, Connecticut in the summer of 2007. In this quiet, bedroom suburb, Jennifer Petit and her two daughters, age 11 and 17, were killed in a home invasion gone horribly wrong; husband and father William Petit was the only member of the family who escaped alive. Framed by the media as a parable of good versus evil, the case and it's perpetrators, Steven Hayes and Joshua Komisarjevsky, became a rallying cry for the death penalty. However, much of the story has been hidden from the general public, and alarming failures in the system reveal another tragedy: this crime could have been prevented at many turns. Told intimately by the victims' and perpetrators' friends and families, as well as the attorneys, journalists, and mental-health professionals involved firsthand in the case, the film takes viewers from the morning of the crime, through the death-penalty trials five years later. Directed, produced and edited by award-winning filmmakers Kate Davis and David Heilbroner, the film suggests that "eradicating evil" is perhaps not the solution, and that larger forces must also be held accountable - or else we pave the way for more senseless tragedy.
