In a future city where memories can be "woven" and "repaired", Lin Mo, a top memory weaver, uses his calm and precise techniques to erase pain and rebuild a perfect life for customers. However, a recurring dream fragment that does not belong to any client - the salty sea breeze, a lone lighthouse and the vague silhouette of a woman - begins to erode his own impeccable memory. When he discovers an old conch that shouldn't be there, he realizes that his proud life might just be a carefully constructed lie. In order to retrieve the forgotten truth, Lin Mo embarked on a dangerous journey upstream and against the entire memory empire.
