Bai Wei, a female forensic doctor, was marginalized in the workplace and suffered cheating and betrayal from her boyfriend in love. When she was depressed, she went for a walk by the river and accidentally fell into the water. When he was about to die, he met a mysterious woman in ancient costume underwater. When she opened her eyes again, she came to an ancient wedding scene. Relying on her photographic historical knowledge, she realized that although her husband was a prince, he was a frail and sickly good-for-nothing, and he would run out of power in three years, and she would also be buried passively. In order to change her tragic ending, Bai Wei resolutely decided to help her husband Gong Dou seize power after failing to escape. She believes that only by standing at the highest point can she ensure her safety. Bai Wei used her forensic knowledge to repeatedly solve strange cases and save innocent women who were pushed out and convicted one after another in the cases, gradually helping herself and her husband accumulate a lot of reputation among the people. Coincidentally, the cases all pointed to the same mastermind, and Bai Wei gradually realized that Li Xun's untimely death in history was not because of it, but because someone deliberately wanted to get rid of the couple.
