The documentary "Risking Light" explores what the world can look like when individuals transform their profound grief and anger into radical forgiveness. Mary Johnson's son was murdered in Minneapolis. Kilong Ung was forced into child slavery by Cambodia's brutal Khmer Rouge regime. Debra Hocking was removed from her loving family as a baby through an Australian government program to relocate Aboriginal children. "Risking Light" tells the story of how these three people brought themselves to forgive the unforgivable.
