Due to a busy workload, Li Kai entrusted his distant aunt, Liu Chunlan, to care for his stroke-stricken mother, unaware that the two had held a long-standing grudge from earlier years. Harboring resentment, Liu Chunlan privately mistreated the elderly woman and even conspired with her son to swindle the mother out of her money and property. After suffering an injury and losing her memory, the mother was on the verge of having all her family assets defrauded. Fortunately, Li Kai had prepared in advance, retrieved surveillance footage to secure all the evidence, called the police to recover the property, and brought the wrongdoers to justice according to the law. Awoken to reality, Li Kai let go of his work to personally care for his mother, wholeheartedly fulfilling his filial duty.
