70 x 7: The Forgiveness Equation derives its title from scripture (Matthew 18:21-22) Peter asked Jesus "how many times shall I forgive someone who harms me? Seven times?" And Jesus answered, "No Peter, not seven times but seventy x seven." 70 x 7 The Forgiveness Equation Two families challenge our rock-hard beliefs as they share the force for revenge or forgiveness in the face of unspeakable horror and grief. Uncommon and compelling stories challenge our deeply rooted beliefs in revenge, retribution and forgiveness. Two sisters lose their parents to brutal murder. Their struggle to forgive or condemn splits a life-long bond. A father witnesses his daughter's slaughter in a monumental terrorist attack. Does he forgive what he cannot forget? His bold and unorthodox connection to the killer's family is the film's force. 70 x 7 The Forgiveness Equation unfolds these stories and struggles. Speaking for themselves, the characters allow viewers to hear first hand how they have coped with unforeseen bereavement, profound feelings of helplessness and rage, and for some, a move towards reconciliation, love and forgiveness. The Stories In this 36-minute documentary, 70 x 7 The Forgiveness Equation, viewers are introduced to sisters Sue Norton and Maude Hills whose elderly parents, the Denny's, are murdered for $61 and an old beat-up truck by an ex-con whose brutal killing spree and ultimate capture guarantee his return to prison with a death penalty conviction. The killer, Robert Wesley Knighton from a poor town in Missouri and known as "BK," was a career criminal from the age of 16. He became an institutionalized convict who, when released with a small prison-issued supply of drugs that ran out, went on a killing rampage.
