McCall (Denzel Washington) has put his mysterious past behind him and is dedicated to living a new, quiet life. But when he meets Teri (Chloë Grace Moretz), a young girl under the control of ultra-violent Russian gangsters, he can't stand idly by. Armed with hidden skills that allow him to serve vengeance against anyone who would brutalize the helpless, McCall comes out of his self-imposed retirement and finds his desire for justice reawakened. If someone has a problem, if the odds are stacked against them, if they have nowhere else to turn, McCall will help. He is The Equalizer.
