Plot

In 1974, Jeffrey Dahmer is a high school freshman living in Bath, Ohio, with his parents, Lionel and Joyce, and his younger brother Dave. Jeffrey develops an obsession with a male jogger he sees every day from his school bus. As a hobby, he collects dead animals that he dissolves to the bone using chemicals from his father, who is a chemist. This hobby is initiated by his obsessive interest in how animals are "fitted together".
