Shen Zhiyao, a nurse abandoned twenty years ago, is suddenly claimed by Shen Wendong, a billionaire, because his only son urgently needs a kidney donor. She gives a cold laugh and produces the paternity test she had prepared long ago. The blood relation is real, but she is not the “lost” child he claims to have found. When her biological father falls to his knees and roars, she learns that her mother’s death was a murder carefully covered up. A deathbed letter from the orphanage director, her husband’s silence, and her younger brother’s trembling all point to one bloody truth: the Shen family was never short of blood relatives. It was only short of scapegoats.
