What motivates someone to take a life? How do murderers remember their lives and crimes? With unprecedented access to high-security prisons all around the country, the creators of Netflix's I Am a Killer set out to get answers to these questions--by talking to the killers themselves.

Most of the killers will die in prison, but each one speaks openly about their pasts and their crimes. Additional interviews--with the families of both perpetrators and victims and the law enforcement officials who worked the cases--reveal the constellations of factors that lead to violent crimes. Each profile features exclusive photographs, documents, and commentary from the documentary producers to give a detailed and balanced account of the crime, leaving it up to readers to decide what was right.
