Veteran Chen Shoujiang dreamed that his grandfather Chen Dehou was entrusted with "protecting the country's destiny". The next day, he found his grandfather digging his ancestral grave and reported the robbery. Criminal investigation captain Meng Tiezhu caught the scene, but archaeological expert Huo Yanzhi dug out a dragon bone full of symbols from his grandfather's coffin. When various forces targeted the Chen family, Chen Shoujiang realized that the dragon's veins were about to be cut off and the ghost tomb was destroyed. Grandpa's dream was not a last word, but a warning. He must join forces with a cold-faced expert and an internet-addicted girl to go to the ground and snatch back the true destiny of the country from the thousand-year-old blood coffin.
