Simply because the fish head pointed the wrong way by a few inches at a family dinner, a storm suddenly erupted. To protect his wronged wife Shen Wanning, Chen Fan completely shattered his blind filial piety and broke away from his biased native family. Little did anyone expect that this minor matter would uncover an astonishing secret buried for thirty years. It turns out that Chen Fan is not of the Chen family bloodline, and behind the switched identity at birth lies an old case deliberately covered up. He broke through numerous obstacles to collect evidence, pierced through hypocritical family affection, and pursued the delayed truth. In the end, his grievances were redressed, he acknowledged his ancestors and returned to his roots, and rushed toward a brand-new life with his beloved.
