After a rookie cop is killed in a drug bust gone wrong, his veteran partner (Chris Halverson) is put on leave. Embarking on an unauthorized investigation, he uncovers a pervasive narcotics network operating under the surface of a rural town. Filming in St. Louis with top-notch local actors and crew, writer/director Josh Guffey turns in a superb, high-octane thriller that features Tony Todd of “Candyman” in a central role. The origins of Guffey’s film can be traced to a true story related by a colleague of his police-officer sister. The case involved an especially talented undercover cop who went into an Illinois town alone to dismantle the narcotics trade — all without the help (or even knowledge) of the local police. Months later, after a host of arrests, he left the organized drug network in disarray. With Guffey drawing further inspiration from Sergio Leone's “A Fistful of Dollars” and Akira Kurosawa's “Yojimbo” — both tales of a stranger playing opposing gangs off each other and emerging as the last man standing — the seed for “All Gone Wrong” was planted, but it took years of research for Guffey to understand the true depth of undercover narcotics work. Touching on many of today’s critical issues, including race, corruption, criminal-justice reform, civil forfeiture, and cycles of incarceration, “All Gone Wrong” incorporates all that Guffey has learned in the 15 years since first hearing that catalyzing story.
