From director Amy Berg: 'Just a year and a half ago, after spending over four years on the same story for CNN and CBS before that, a paedophile priest named Oliver O'Grady decided he would participate in the film I wanted to make. It became Deliver Us From Evil -- the story from inside the sickest mind possible, the secrets that were meant to stay in the private files and crypts of the Roman Catholic Church, and the blind trust in those they perceived as God's messengers that left families with no faith and children with no innocence. After filming for a week and a half, the then defrocked priest mentioned he might need to move to Canada after this film comes public. Seeing the pain, corruption and missed opportunities to provide ministry to those in need was truly a tragic story to watch and the loss was more devastating than I ever imagined. It was so difficult to be so close to such a horror story that in the priest's words "never should have happened.".

In 2001, Andrew Bagby, a medical resident, is murdered not long after breaking up with his girlfriend. Soon after, when she announces she's pregnant, one of Andrew's many close friends, Kurt Kuenne, begins this film, a gift to the child. Friends, relatives, and colleagues say warm and loving things about Andrew, home movies confirm his exuberance.
Andrew's parents, Kathleen and David, move to Newfoundland, Canada where the ex-girlfriend has gone. They await an arrest and trial of the murderer. They negotiate with the ex-girlfriend to visit their grandchild, Zachary, and they seek custody. Is there any justice; is Zachary a sweet and innocent consolation for the loss of their son?
