Fifteen years ago, a "nursery rhyme murder case" occurred in a coastal town. The murderer imitated the plot of the British nursery rhyme "Ten Little Soldiers" and committed the crime. All five victims died in the manner of the nursery rhyme, and the case eventually became an unsolved case. Fifteen years later, similar killing techniques reappeared, with nursery rhyme cards and a wooden soldier ornament engraved with "To Be Continued" appearing next to the new victim. Lin Shen and Lu Wei formed a partnership to investigate, only to discover that the case not only involved the truth of an old case 15 years ago, but was also inextricably linked to the secrets of local wealthy families and the black market for organ trafficking. As the investigation deepens, Lin Shen and Lu Wei gradually become the targets of the murderer, and their respective secrets are gradually revealed in danger.
