This downward spiral culminates in the discovery of the video-tape made by Oliver recording the final moments of his victim’s life. Witnessing the courtship between the two men, and the final atrocity of the killing, Katie hits rock bottom. At the base of her own emotional sanity, she discovers the inner strength to pick herself and begin the smallest steps to rebuilding her life.
