Working as an undercover investigator for the New York City District Attorney’s Office, ex-private eye Shannon (John Compton) spent most of his time infiltrating the New York underworld.
Hijacking rings, prostitution, narcotics, and any other source of mob income were appropriate targets for his sleuthing.
Shannon’s contact at the DA’s office was First Assistant D.A. Al Bonacorsi (Ralph Manza).
