Through the voices of survivors, journalists, and excerpts of legal depositions, Diabolical dips its toes into the world of the Epstein Files--a partially released collection of millions of documents, images, videos, e-mails, and other records pertaining to criminal investigations undertaken by the FBI of convicted paedophile Jeffrey Epstein. The records were reluctantly released after much political pressure, and millions of files are still yet to be made public. Many of the world's billionaires, and most powerful figures in politics and mainstream culture appear in the files, as persons in the orbit of Epstein and his life trafficking teenage girls for sex. The film lays bare how the rich evade the legal and justice system with their wealth and power, and raises some conspiratorial questions about just who Epstein was, along with his connection to power and influence in the United States.
