On the eve of the confiscation of the house of the Marquis of Wu'an, An Nuan, the humblest wet nurse, was asked to take away the infant young master and become his "mother". She took her biological daughter and this hot blood with her, and embarked on a dead end in the light of the sky. The loyal servant paved the way with his life, and the young girl used her wits to survive. She struggled to survive in the gap between investigation and pursuit. From the dog cave in the Hou Mansion to the vast sea of people, she must make this child disappear completely, keep her name anonymous, and guard a secret buried with the old prosperity until the end of the world.
