An ordinary genetic test revealed the cruelest truth about the seven-year marriage - none of the three children was biological. The moment engineer Ying Qingfeng got the test report, his life completely collapsed. The loving family he once thought was just an illusion built on lies. The betrayal of his wife Lan Weiwei and the completely different paternal origins of his three children pushed him into the abyss of truth and emotion.
From shock and pain to decisive investigation, Ying Qingfeng embarks on a difficult road to expose betrayal and find justice. Secret investigations, court confrontations, and public opinion storms followed one after another, and the psychological crisis of the three children after their identities were exposed made him struggle between hate and love. When the legal verdict came down and the property and children belonged, he realized that blood ties could be forged, but the emotions he had spent for seven years could no longer be let go.
In the collision between social ethics and personal dignity, Ying Qingfeng moves from victim to redemption. He began to think: Is the identity of a father defined by genes, or is it forged by love and responsibility? "Not the Father" is not only a suspenseful tracking of betrayal and truth, but also a profound tragedy about human nature, law and non-blood family ties.
