Don't Look Back [Blu-ray]

After months of being scared to go outside after a traumatic experience, Caitlin went for a jog and became one of the many who witnessed a man getting beaten to death. After the media labeled the bystanders who did nothing to stop the slaying as "bad samaritans", one of them falls to death from his apartment not long after, convincing Caitlyn that someone or something is after all of them.
