On the day he was laid off from the company, Lu Chen bought an old tape recorder for twenty yuan. When his fingers touched it, he heard a sentence left seven years ago: Don't believe the suicide note, the account book is hidden in the third broken key. From then on, every old thing may reveal to him a truth buried by time: a subcontracted dowry, an unclaimed medal, a fake worth tens of millions at auction, and the last key left by his father before he disappeared. Others rely on their eyesight to identify treasures, but Lu Chen relies on old objects to speak. He started from the scrapyard in the south of the city and went to antique streets, pawn shops and top auctions. But as he got closer and closer to the truth, he finally discovered that some old things were not that no one dared to touch, but were waiting for someone who could hear them.
