Twenty years ago, Georgia Deputy Kyle Dinkheller was brutally murdered along a cold stretch of highway in rural Georgia in what has become the most infamous police dash cam video ever captured. The footage itself has been seen around the world millions of times, often attached to false stories and rumors. In 2017, one police officer sought to understand who that deputy was outside of one bad day and, in doing so, found a seed of truth that turned a short film into a feature-length investigation.
