Surgeon Ye Zhenzhen became a doctor and became the "evil stepmother" despised by everyone in the compound in the 1980s.
Her husband is indifferent, her husband's family dislikes her, her neighbors give her advice, and she also has a frail and sick stepson named Xiaobao who is destined to die young.
Ye Zhenzhen originally wanted to live a Buddhist life, but Xiaobao died one after another in various strange accidents: death from illness, car accident, illness, poisoning...
Whenever Xiaobao dies, time will be reset to the moment when she first entered the door.
After experiencing twenty-one painful reincarnations of death, Ye Zhenzhen finally discovered in despair: in order to break the cycle, she must uncover the true murderer hidden in the darkness of the times from the cause of the treasure's death.
But Lu Chen, who was feared by the whole town and regarded as a "gangster and traitor", guarded the alley of the black market in the middle of the night every reincarnation, handing her a batch of life-saving medicine:
"This is the 22nd time, Zhen Zhen, how are you going to save him in this life?"
In the beginning, she was never the only one trapped in the time cage.
