We follow Dahmer through his troubled home life, burgeoning deviant behaviour, as well as his relationships with his 'friends' (more like bullies), whom he gains through odd behaviours, such as faking fits in school. The source material, written by John (Derf) Backderf, provides an insight into the High School years of this his (then) friend, Jeffrey Dahmer, who is most infamous for his serial killing spree of his male lovers and also his cannibalistic tendencies. Based on the graphic novel of the same name, My Friend Dahmer, attempts to take a new perspective on the 'serial killer' film.
