My friend Riccardo is fascinated by Jeffrey Dahmer, one of America's most famous serial killers. Riccardo recognizes himself in this man, a homosexual like himself, treated by others as a monster, and for whom he feels a love that he has never been able to feel in his own life. I travel with him to Milwaukee, the city where Dahmer committed his murders, to film him as his encounter with reality puts his fantasy to the test.
