A look at when serial killer Jeffrey Dahmer was arrested in Milwaukee in 1991 and sentenced to 957 years in prison for killing 17 people and dismembering their bodies. In particular, here we meet the individuals surrounding Dahmer during and after his hidden spree, including Milwaukee Medical Examiner Jeffrey Jentzen, Police Detective Patrick Kennedy, and neighbor Pamela Bass. Interviews with them are interwoven with archival footage from Dahmer's life, culminating in the facade of an ordinary man leading an ordinary existence.
