When modern medical graduate student Lin Xia touched a green jade hairpin from the Ming Dynasty in the laboratory, she was accidentally drawn into a space-time vortex by a blue light and traveled to a strange ancient town. Wearing a modern white coat, she lay on the street and was rescued by Shen Yan, a young doctor from Jishitang. Lin Xia, who lost his memory, temporarily stayed in the hospital, but was put in danger due to the mysterious blood stain on his neck and the investigation of Lu Zhao, the commanding officer of the Jin Yiwei.
As the investigation deepens, Lin Xia discovers that the missing green jade hairpin involves a secret buried by history - the lotus pattern on the hairpin hides a blood contract. The red lantern of the old plum tree that she is inexplicably familiar with, Shen Yan's hesitant warning, and Lu Zhao's perseverance in tracking all imply that she has a bond with this jade hairpin that transcends time and space. When night fell, she could actually feel the weak pulse of the hosta, calling her like a heartbeat to uncover the truth.
In the intertwining of memory fragments and ancient medical skills, Lin Xia must unravel the ancient motto "Jade has spirit, connected by blood contract", find a balance between the pursuit of Jin Yiwei and the protection of Shen Yan, retrieve lost memories, decipher the secret of the hosta traveling through time and space, and find the method and courage to return to the modern era amid the gradually emerging historical conspiracy.
