Before his death, the tomb robber Jiang Mazi left behind a treasure map. According to legend, this treasure map hides a shocking secret. Those who can crack this secret can obtain endless treasures. The northern tomb robber Lao Bi (played by An Zehao), the southern tomb robber Zhuo Jianliang (played by Mo Shaocong), the thief Hao Qi (played by Duan Bowen) and Wu Kui (played by Nie Yuan), who had just been released from prison, heard the news and came to the northwest desert according to the clues provided on the treasure map. Along the way, the group encountered countless dangers and setbacks, and their own ghosts also added different dangers to this tomb-robbing journey. In the end, they entered the treasure tomb, but found that it was already empty, and the sound of the mechanism made them know that they were already in another trap.
