After a bizarre car accident, modern forensic doctor Jiang Wan Ning traveled through time and became an ancient bride. On her wedding night, she discovered that her groom, Xiao Yanheng, the king of Jingan, was secretly investigating a serial murder case. The deceased were all newlyweds, their faces disfigured, and their death conditions were strikingly similar to the last unsolved case she handled in her previous life.
She was forced to play the role of a gentle princess, but on the wedding night, she found a trace of modernity at the base of the wedding candle - a stainless steel screw.
Two murder cases thousands of years apart were connected by the same murder weapon. Jiang Wanning had to use her forensic knowledge to secretly assist Xiao Yanheng in solving the case, but gradually discovered that the cold-faced prince's approach to her was a careful calculation from the beginning.
And when she finally got close to the truth, she was shocked to realize that the murderer had been by her side all along.
