The documentary, which took 10 years to shoot, focuses on the life of Steven Avery. Steven, who was born and raised in Manitowoc, works with his father and older brother in a junkyard. After a woman was raped and harassed on her way to Manitowoc, this changes Steven's life. As a result of the old-fashioned investigation, when DNA analyzes were not very good, Steven Avery is thrown in, even though he says he is innocent. After serving 18 years in prison, Steven Avery is proven not to be the murderer, and the real criminal steps in. Steven, who was innocently imprisoned for all these years, becomes a suspect in a new case while seeking his rights.
