The premise arrives fully formed and immediately falls apart, which somehow makes it more entertaining than if it had held together. You're watching a show that knows it's absurd, vampires in collars, a half-breed messiah nobody asked for, a plot that pivots hard enough to whiplash, and commits anyway. The landscapes are gorgeous enough to distract you from the fact that nothing makes sense, and that's the entire appeal.

Sixty years ago, a strange insomnia kept people awake for over a week and drove the sleepless victims mad. The medicine made to cure it had a terrible side effect: those treated became vampires. Humanity fought the new species and won, but some vampires lived on. Mi Liu, born to a human and a vampire, is meant to be the Child of Hope who will bridge the two peoples. After leading a bank robbery, he is arrested and sent to a special National Defense Agency prison that keeps watch over vampires. When he tries to escape with Anji, strange monsters attack, and he learns the prison stands on Blue Town, the old capital where vampires first appeared. Why are vampires confined there, and what are these creatures? Mi Liu and his companions must fight for the answers in this supernatural action mystery.
