et in America’s Heartland, Making a Murderer follows the harrowing story of Steven Avery, an outsider from the wrong side of the tracks, convicted and later exonerated of a brutal assault. His release triggered major criminal justice reform legislation, and he filed a lawsuit that threatened to expose corruption in local law enforcement and award him millions of dollars. But in the midst of his very public civil case, he suddenly finds himself the prime suspect in a grisly new crime.
