Emergency physician Yu Qingyin never imagined she would reunite with her adoptive older sister, Xie Zhiyao, who left without a word when she was seventeen, in this way: as the defense lawyer in an "accidental" car crash, standing by her hospital bed and demanding evidence.
A patient's delirious murmurs, falsified medical records, the truth about a death covered up twenty years ago... Every clue points to a shadow known by the codename "Red Kite," which has long taken root in the veins of the medical System.
In pursuit of their father's dying words, the two women are forced to work together:
One wields a scalpel, fighting for the truth on the brink of life and death;
The other grips the law, cutting through a labyrinth of lies to expose the dark truth.
But they don't know that when Red Kite finally breaks its silence, what burns will be more than evidence of crime...
It will also be the bond between them, regained after being lost, and now all the more precious because they can hardly bear to lose each other again.
"Qingyin, this time, we won't face it apart."
"Zhiyao, some wounds a scalpel can't heal need the law to stitch them closed."
Theme: Use truth as a scalpel to excise the cancer in the System, and an old love as a hemostat to stitch the wounds of an era
