In the film, McCall discovers that his new friends in a small town in South Italy are intimidated by Camorra members, where he sets out to save them from the threat.

Filming began on October 10, 2022 in Italy on the Amalfi Coast and continued in the region until November 20, after which it moved to Naples in early December, before wrapping production in Rome by January 2023.

Gio brings Robert to a remote coastal Italian town called Altamonte where he is treated by small-town doctor Enzo Arisio.

Robert makes an anonymous phone call to CIA officer Emma Collins to tip her off about the winery's role in the illegal drug trade disguised as normal business transactions in Sicily.

Collins and other CIA operatives arrive at the winery and find millions in cash along with bags of fenethylline tablets hidden in a storeroom, confirming Robert's suspicions.

Meanwhile, members of the Camorra harass and kill villagers in an attempt to coerce them out of their housing and take over Altamonte for commercialization purposes.

Robert overhears Marco Quaranta, a high-ranking Camorra member, pressuring local store owner Angelo for payments.

Back in Langley, Virginia, Collins receives a promotion for her role in ending the Altamonte drug trade.

[19] In May 2023, Marcelo Zarvos was brought in to score the film's music after previously collaborating with Fuqua in Brooklyn's Finest (2009), What's My Name: Muhammad Ali (2019), The Guilty (2021) and Emancipation (2022).

The website's consensus reads: "Another entertaining outing from Antoine Fuqua and Denzel Washington, The Equalizer 3 mostly makes up for its formulaic story with generous helpings of cathartic action.

"[30] Kyle Smith of The Wall Street Journal wrote, "For those who can tolerate extreme violence, The Equalizer 3 is diverting enough.

If the script is so-so, the beautiful Italian locations, Mr. Washington's still-world-class charm and an eerie, frightening musical score by Marcelo Zarvos lift it.

[33] In August 2023, Fuqua stated that there have been discussions to develop a prequel movie detailing the origins of Robert McCall.
