Su Suining, an extraordinary female emperor from ancient times known for her decisive and ruthless rule, unifies the realm and unexpectedly travels to the modern era on the very day she ascends the throne. She awakens in the body of a fake heiress who is also a mistreated daughter-in-law in a wealthy modern family. The family's rotten old-fashioned ideas clash with her own principles. Having conquered a palace full of dangers to become empress, she now intends to seize the power that rightfully belongs to her in the modern world. She will train her spoiled husband into a worthy, high-quality imperial consort. Her contemptuous mother-in-law and sister-in-law will be won over and become her devoted admirers, while her disreputable father-in-law will be made to disgrace himself in public. The empress is determined to set the household straight. As her husband turns into a devoted wife-pleaser and shyly asks to date her, the empress makes one thing clear: Sorry, I'm not here for romance. I'm here to seize power!
