In a future city where memories can be edited and deleted, Lin Mo, a top "memory fabricator", can weave perfect dreams for clients, but cannot repair his own broken memory about his deceased wife. A mysterious commission broke his peaceful life: a widow named Yi Shu asked him to sneak into the deep memory of her late husband, the genius scientist Jiang Han, and retrieve a "last word" that had been forcibly forgotten. After Lin Mo dived into the dangerous sea of memory, he discovered that this was not a simple emotional repair, but a huge conspiracy that could subvert the order of the entire city. The truth he pursues is not only related to the fate of his client, but also closely related to his own lost past.
