Plot synopsis:
Robert McCall (Denzel Washington) is a retired black ops operative who lives quietly in Boston, Massachusetts and works at a Home Mart hardware store; McCall befriends many of his co-workers and helps a security guard trainee named Ralph pass his qualification exam. McCall promised his recently deceased wife that he would leave his old life behind. Unable to sleep, McCall spends some late nights reading in a 24/7 diner where he befriends Alina (Chloë Grace Moretz), a teenaged prostitute for the Russian Mafia; McCall regales Alina with philosophical interpretations of the book he is reading (The Old Man and the Sea). One night, Alina is hospitalized following a brutal beating by her pimp, Slavi (David Meunier). McCall enters a restaurant owned by the Russian mob and offers to buy Alina's freedom from Slavi for $9,800, but Slavi refuses, dismissing McCall as old and impotent. Failing in this approach, McCall considers the room, estimating it would take him 16 seconds to clear it. He subsequently kills Slavi and four of his men with skillful close combat efficiency. To slight dismay, McCall realizes that it took him 19 seconds to accomplish his task and quietly lectures the dying Slavi that his death could have been avoided had he taken the money.
In response to the death of Slavi and his crew, Russian Mafia boss Vladimir Pushkin (Vladimir Kulich) sends his enforcer, Teddy Rensen (Marton Csokas), to Boston to find and eliminate the culprit. In the meantime, Ralph withdraws his security guard application and instead goes to work with his mother at the family restaurant; McCall learns that the restaurant was set on fire by corrupt policemen as an act of extortion. McCall confronts the corrupt policemen, beats them, forces them to pay back all the money they have extorted, and threatens to publicize their crimes. Ralph then returns to Home Mart and passes his test, becoming a security guard at the store.
Rensen determines that McCall is the culprit in the attack on Slavi and his crew. McCall repeatedly outsmarts Rensen and his pursuers and completes more acts of vigilantism. McCall then visits retired CIA operatives Susan (Melissa Leo) and Brian Plummer (Bill Pullman) in Virginia; Susan helps him acquire intelligence on Pushkin's activities. It is revealed that Rensen's real name is Nicolai Itchenko and that he is an ex-Spetsnaz who ran a wing of the secret police; Susan describes him as "a sociopath with a business card". Brian reveals to McCall that he had a "nice funeral"; the Plummers are relieved, though not surprised, that he is still alive. After McCall leaves, Susan remarks to Brian that McCall was not actually looking for help, but was asking for permission.
After returning to Boston, McCall captures Frank Masters (David Harbour)--a corrupt policeman bribed by Pushkin--by trapping him in his car and flooding the vehicle with tailpipe exhaust to force him to cooperate. Masters relents and helps McCall destroy one of Pushkin's local money laundering operations. McCall confronts Itchenko at dinner, pledging to bring down Pushkin's criminal enterprise. When McCall destroys a container ship Pushkin used to smuggle goods, Pushkin orders Itchenko to kill McCall; Pushkin adds that until the deed is done, Itchenko may not return home to Moscow.
Itchenko and his men go to the Home Mart and take Ralph and several of McCall's other coworkers hostage, threatening to kill them if McCall does not surrender. McCall enters the store, disables most of the lighting, and tells Ralph to get the hostages to safety. McCall then kills Itchenko's henchmen one by one using booby traps constructed with items in the store. After a struggle between McCall and one of Itchenko's men, Ralph comes back to pull the injured McCall out of the store, but is shot in the leg himself. McCall tells Ralph to turn on the electricity at the breaker box in exactly 40 seconds, giving him his digital watch for precision. McCall sets up small containers of propane and oxygen in a microwave oven. The electricity turns it on, causing an explosion that kills the last of Itchenko's men. Afterwards, McCall confronts Itchenko and kills him with a nail gun.
Later, McCall then travels to Moscow, confronts Pushkin, and sets a trap which electrocutes and kills him. McCall returns to Boston and is approached by Alina, who has recovered from her wounds, found a legitimate job, and taken up reading. Alina thanks him for giving her a second chance. McCall is inspired to continue using his skills to help people in need and posts an online advertisement, now identifying himself as "The Equalizer". He soon receives another plea for help and agrees to answer it.
