To see whether his children were truly filial, elderly traditional Chinese medicine doctor Shen Henian stages his own death, leaving behind a mystery involving ten million yuan in demolition compensation and a family-inherited secret prescription. His five biological children appear grief-stricken, but soon quarrel over their own interests and repeatedly shirk their responsibilities while taking turns caring for their mother, Su Wanqing. Meanwhile, their financially struggling adopted son, Zhou Nian'an, devotedly looks after her and scrambles to raise money for her medical treatment. When the truth comes to light, Shen Henian entrusts the family business to Zhou Nian'an to preserve the legacy of traditional Chinese medicine, while giving his biological children a chance to turn over a new leaf. After enduring these trials, the family reunites and rediscovers the meaning of family, learning that true filial piety lies in sincerity and companionship.
