According to the show's Amazon Prime summary, "Vinnie Terranova does time in a New Jersey penitentiary to set up his undercover role as an agent for the OCB (Organized Crime Bureau) of the United States. His roots in a traditional Italian city neighborhood form the underlying dramatic base throughout the series, bringing him into conflict with his conservative mother and other family members while acting undercover as syndicate enforcer."
"Wiseguy" aired for four seasons, from 1987 to 1990. Over the years, it garnered seven Emmy nominations, but no wins. The entire show is streaming on Pluto, Sling TV, Tubi, Vudu, and Amazon Prime.
While you may not remember the show, you've definitely heard a term that originated from its then-unconventional story structure: the story arc.
