ONCE UPON A CRIME: The Borrelli - Davis Conspiracy, follows the extraordinary story of two innocent men whose lives are torn apart solely because of their race. Mike Borrelli, an Italian-American NYPD detective and his partner Bob Davis, one of the first African-American detectives in New York, are convicted for committing first-degree murder for one of New York's most notorious crime bosses. But Mike Borrelli and Bob Davis are innocent. Law enforcement agents know it too, but they are hell bent to connect the murder to the mafia; incredibly, they give the known gunman immunity and place him into witness protection in exchange for his false testimony against the two officers. This film reveals the shocking details of this unimaginable injustice as the filmmakers embark on a tireless search for the one known gunman, still in hiding.
