Since her childhood in Colombia, Gabriela has kept a scrapbook of newspaper articles about grisly murders. The clippings are illustrated by Gabriela's visualizations of each murder which, over the years, have grown more sophisticated and in-depth. It is while leafing through her scrapbook that Gabriela hears a television report of a new serial murderer, the Blue Blood Killer. Insouciant and smiling as ever, Gabriela applies for a job at Post Forensic Cleaning Service and is hired on the spot. Gabriela is determined to clean up after one of the murders of the Blue Blood Killer, and after he strikes again, she happily volunteers for the clean-up job. After one day of cleaning, Gabriela sneaks back to the crime scene where she recreates the dance of death of both victim and killer. However, unknown to her, the Blue Blood Killer has been present throughout the dance. For the first time, he is faced with someone whose obsessions mirror his own. The stage has been set for one more mess to be cleaned.
