Elena, a top enforcer for a gang, is ambushed and kidnapped mid-mission, only to wake up and discover that her kidnapper is none other than her long-lost twin sister, Catherine — the chairwoman of the VV Group — who, terminally ill with late-stage cancer and just three months to live, faces her billions in inheritance falling into the hands of her three good-for-nothing siblings: Jeff, the lovestruck second brother utterly bewitched by the scheming "green tea" Jessica; Jack, the gambling third brother drowning in tens of millions in debts; and Nina, the timid youngest sister bullied at her ballet company. Catherine begs Elena to take her place and discipline the siblings with an iron fist to protect the family legacy, and so Elena transforms into an icy, imperious chairwoman and makes her triumphant return: kicking Jessica to the curb in public, exposing the frame-up Jessica staged on herself, winning justice for Nina at the ballet company, freezing Jeff's accounts, and seizing Jack's beloved signed helmet to force him into line — thus begins a family-taming saga of fighting fire with fire.
