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.
A plague of endless wakefulness once ravaged humanity, driving millions to madness. The cure came with a terrible price: those treated became vampires. War nearly extinguished the species, but survivors endured in the shadows. Now Mi Liu, a half-human, half-vampire hybrid, carries the weight of being a symbol for peace between two worlds. His criminal past catches up when authorities capture him during a bank heist and lock him away in a maximum-security facility run by the National Defense Agency. The prison holds far more than just vampire inmates. Mysterious creatures lurk in the depths, and when an escape attempt goes sideways, Mi Liu discovers the installation sits atop something far older and more sinister than anyone suspected. Trapped between guards hunting him and monsters closing in, Mi Liu must uncover the truth about his origins and what lies beneath the prison before the darkness swallows everyone inside. Action, mystery, and moral ambiguity collide as former enemies become unlikely allies in the fight for survival.
