Chen Mo, an ordinary construction quality inspector, did everything he could to save his seriously ill wife Yang Xue: selling her wedding house, borrowing loan sharks, working risking her life, and making bone marrow-level sacrifices to cure her. However, Yang Xue's recovery became the beginning of his nightmare.
Yang Xue and his selfish and greedy family members - mean Yang mother, cold-blooded father Yang, parasitic brother and sister-in-law, and vain sister - regarded Chen Mo's kindness as a bottomless pit and frantically squeezed money, even forcing him to sign a huge IOU. When Chen Mo expressed concern, he was falsely accused of domestic violence by Yang Xue, and the Yang family even came to beat him up, pushing him into litigation hell.
Alone in the face of carefully constructed perjury and cold calculations, Chen Mo experienced the suffocation and despair of being bitten by his lover and having no one to help him. The lover he desperately saved not only used his kindness as a stepping stone, but also inflicted mental torture on his biological daughter Chen Nianen.
Protecting his elderly loving mother and innocent young daughter became Chen Mo's only glimmer of light in the abyss. But the vicious harassment from the Yang family followed him like a vicious dog biting at the peace he had struggled to rebuild. From a lifesaver to a "domestic violence defendant", Chen Mo struggled with betrayal and frame-up. Can he regain his dignity in the cracks of the law and protect the remaining family ties? When the poplar flowers have fallen, the prosperity has faded away, and the marrow has been sucked dry, can he, on top of the ruins, build a wall of salvation for his loved ones that can withstand the evil wind? This is a story about extreme sacrifice, encountering the evil of human nature, protecting family ties with tenacity, and regaining a new life in the glimmer of light.
