Modern woman Shen Qingwan unexpectedly time-travels, becoming a discarded empress cast into the Cold Palace. In the Cold Palace there is also a group of forgotten people: Mammy Liu with a venomous mouth and a soft heart, Consort An with superb medical skills, Responder Liu with deft hands and clever minds, the honest and nimble young eunuch Zhao Xiaodun, and the honest and down-to-earth cook Uncle Fu. From suspicion to trust, they gradually become the core of Shen Qingwan's startup team.
