In a future city where memories can be accurately removed, Lin Mo, the top "memory liquidator", erases the pain of his clients with the calmness of a scalpel. He firmly believed that forgetting was the ultimate salvation, until during a routine operation, a memory that belonged to no one - a rainy alley, a red umbrella, a vague silhouette of a woman - invaded his mind. This ghostly fragment pried open his solid reality like a wedge. In order to pursue the truth, Lin Mo embarks on a dangerous path. He will discover that buried under the sea of oblivion he has built himself is not only the past of others, but also his own stolen life.
