Mata, Que Nós Limpamos o Sangue (1996)

Gabriela, a Colombian immigrant, is obsessed with understanding violent crime. The current string of murders by "The Blue Blood Killer" of affluent Miami socialites provides her with fodder for her scrapbook of death. She lands a job with a post-murder cleaning service and during a Blue-Blood clean-up job, discovers evidence that police have overlooked.
