In 1984, a British journalist named Arthur Stuart is tasked with investigating the life and mysterious disappearance of a glam rock star from the 1970s. As Arthur delves into the story, the narrative flashes back to the 1970s, revealing the rise of Brian Slade, a provocative and androgynous musician who captivates the nation with his flamboyant performances and alter ego, "Maxwell Demon." Slade's music and image challenge societal norms and inspire a devoted following, but his career is marked by controversy and a complex personal life, including his relationship with American rock star Curt Wild.

As Arthur continues his investigation, he uncovers the intertwined destinies of Slade and Wild, exploring the impact they had on fans and the music industry. The journalist's journey is also a personal one, as he reflects on his own experiences growing up during the glam rock era and the influence it had on his identity and sexuality. The early part of the narrative is rich with the decadence and rebellion of the time, encapsulating the excitement and the eventual fallout of the glam rock movement as it faced backlash and commercial decline.
