A fish store ajumma who dreamed of a better life for herself, a housewife who was an orphan growing up, and the daughter of a chaebol who was raised like a delicate greenhouse flower all come together for retribution in this story. They are an improbable trio that would not have come together under any other circumstances, yet they band together to exact their respective vengeances. They will end up being close friends despite the fact that they first work together in a criminal enterprise. "Buam-dong Revenge Social Club" is the name of the webtoon that this anime is based on.
