An accidental car accident caused Lu Ming to lose nearly three years of memory. When he woke up in the hospital, he was faced with a room full of children's supplies, a large number of pictures of girls on his phone, and soft words of "Daddy". He was completely at a loss. He didn't even know that he had a four-year-old daughter, Lu Xiaotang.
After returning home from the hospital, Lu Ming found traces of mother and daughter's life everywhere in the house, but there was no trace of the child's mother, Shen Mu. He followed the clues and learned that he had exposed problems in the company and was plotted against by Vice President Su Mingyuan. The car accident was not an accident. The other party also forged resignation records and secretly monitored the situation in an attempt to erase all evidence. Fortunately, Shen Mu was aware of the crisis early and collected evidence of Su Ming's data fraud and reselling of the company's core technology in advance. He also handed the clues to Lu Ming one by one through USB flash drives, anonymous entrustment, etc.
During the process, the kind-hearted colleague Lin Xiaohe, the coerced technical director Zhao Heng, the knowledgeable Zhou Zhiyuan and others successively extended a helping hand and continuously added key information. While Lu Ming clumsily learned to be a baby daddy, taking good care of Xiaotang who relied on him, he followed the clues and gradually uncovered the complete criminal chain with investment tycoon Meng Guangping as the mastermind behind the scenes.
He met Shen who was hiding in secret several times. The two cared about each other but were placed in a dangerous situation. In the end, Lu Ming integrated all the evidence and took the initiative to report the case to the economic investigation department. In this turmoil intertwined with family affection, conspiracy and redemption, the amnesiac dad continues to grow on the road to protecting his daughter and pursuing the truth. All perpetrators will eventually be punished, and the separated family also has hope of reunion.
