When the city museum restorer {Su Yan} was restoring an ancient painting from the Qing Dynasty, he used his "detail insight" ability to discover that the patterns on the clothing of the characters in the painting contained miniature codes. Professor of History Department {Lu Shiyan}, who was studying family history in the Qing Dynasty, noticed the details in the paintings she published and offered to cooperate. The two followed the code and discovered that the ancient painting was related to the massacre of the Shen family a hundred years ago, and Su Yan was a descendant of the Shen family. Cultural relics dealer Zhao Kun determined that the password pointed to a "family treasure" and set up traps many times to seize clues and steal ancient paintings. Su Yan and Lu Shiyan joined hands to visit the old site, decipher the codes, and resolve the crisis with their professional skills. They finally found the family diary and revealed the truth behind the man-made massacre. Zhao Kun was captured by the police, and the Shen family's injustice was cleared up.
