Just as McCall considers ending her work as The Equalizer, she's pulled back in when she takes on Detective Marcus Dante as a new client who needs her help to find an untraceable group of bank robbers.
McCall finds herself in the crosshairs of a foreign government's intelligence agency when her friend Mira, a diplomat's daughter, seeks McCall's help to find her missing brother. Also, Dante faces suspicion from a fellow detective newly tasked by the district attorney to find the vigilante known as the Equalizer.
McCall is hired by a concerned mother who suspects her teen son has joined a local gang, leading McCall to the boy's surprising motivation behind his spiraling behavior. Also, Delilah faces anxiety as she prepares to speak at her friend Jason's memorial service, and Dante worries when the new detective pursuing McCall sets his sights on unmasking the people closest to her.
