An accident during the rainy season in the south led antique restorer Lin Xiao to reunite with the cherry blossom silver bracelet engraved with "Xixiao" at the second-hand market - it was the token the two agreed to buy when their sister Lin Xi disappeared five years ago. The dark red blood stains stuck on the chain, anonymous death threats, and Chen Nian, a missing girl with the same name in the file, involved her in an old-object mystery that spanned five years.
The cherry blossom iron gate in the abandoned alley, the mysterious man wearing a mask, and the jade ring that hides secrets. Every old object tells the hidden truth. When Lin Xiao followed the clues and found the abandoned warehouse, he faced not only his missing sister and best friend, but also the sin and obsession behind the old things. The mysterious old lady who appears at the end and the sudden change of engraving on the bracelet lead this "echo" into a deeper fog - some old objects remember things far longer than people.
Purpose: 1. Old objects hide the truth, and obsession illuminates hope. 2. The silver chain leads to the mystery, and the glimmer of light breaks the desperate situation. 3. Old objects record the past, and persist in finding the way back.
