A pair of siblings, Kane and Ella, accidentally broke into a cursed time and space rift while escaping from their adoptive parents, and became involved in a conspiracy that spanned time and life and death. Fifteen-year-old Kane took his 12-year-old sister to escape from the oppressive countryside and go to the big city to make a living. However, they were attacked by vicious dogs in the wilderness and were saved by the mysterious undead army. Following the traces of the undead, they traveled to a strange hut in the British countryside in the 20th century. They were taken in by the seemingly kind-hearted Martha and his wife, but in fact they became prey in a cage - the brother and sister were given control potions and were dying of inhuman torture!
In desperate imprisonment, Ella relies on the bone language she learned from ancient books when she was young, and Kane accidentally forms a bone contract with the remnant soul of the undead lieutenant, awakening the ability to control bone fragments and listen to the whispers of the bones of all things. On a rainy night, they set off for revenge and returned to the city to make a living. Three years later, the brother and sister's "stable life" was broken by a mysterious death, and a conspiracy spanning 18 years was gradually revealed.
Through the interweaving of "modern urban suspense + British rural fantasy + family conspiracy epic", the "bone language" is used as a clue to connect 18 years of conspiracy and century-old grudges.
