When police detective Elane goes deep into the dark forest to investigate her parents' murder case, she encounters not only bloodthirsty monsters, but also the inhuman being Alicea who guards the seal. The fate of "Night Watch" and "Key" binds them. On one side is the hunting mission that must be completed, and on the other side is the undercurrent of fatal attraction. Amid the torn apart of lies and truth, race and fate, they must make a choice: continue the ancient sacrifice, or work together to rewrite the red rules?
Intention: Eternity or ephemerality, how to choose!
