Archaeology professor Yu Qinghuan unexpectedly transmigrates into the past and becomes the notorious "Doomed Consort" from history. She discovers that the original owner of her body was imprisoned in the Cold Palace and is in grave danger, so she decides to use her knowledge of history to change her fate.
Faced with poisoned wine sent by the empress, Yu Qinghuan skillfully maneuvers around the threat, using historical prophecies to pique Emperor Xiao Jingheng's interest and successfully escape the danger of the Cold Palace.
Xiao Jingheng appears cruel on the surface but hides his true nature. Fascinated by Consort Yu, who can "foresee the future," he enters a dangerous game of trust and testing with her.
The empress and the state preceptor join forces to frame Yu Qinghuan. Everyone at court sees her as a demoness bringing ruin to the kingdom, and she must find a way to survive amid the struggles between powerful factions. Yu Qinghuan discovers that the original owner of her body may not have been a true "demon consort" at all, but a victim of political intrigue, with a greater palace conspiracy lurking behind it.
