The Equalizer returns for an action-packed fourth season starring Queen Latifah as vigilante Robyn McCall, an anonymous guardian angel who uses her skills as a former CIA operative to help the oppressed and the downtrodden. Robyn balances her clandestine career as a vigilante with her life as a working mother, raising her daughter Delilah (Laya DeLeon Hayes) with the help of her aunt Vi (Lorraine Toussaint). Robyn fights for justice alongside Melody "Mel" Bayani (Liza Lapira), a sniper from Robyn's past, Harry Keshegian (Adam Goldberg), a brilliant white-hat hacker, and Marcus Dante (Tory Kittles), an NYPD detective who has come to recognize the need for Robyn's vigilante justice. This season picks up where last season's cliffhanger finale left off, with Robyn racing to save the team after their lives are endangered by her former CIA colleague.
