Plot.
60 years ago, some people began to suffer from a strange case of insomnia that struck the entire population. Unable to sleep for more than a week, a large number of people become completely sleep deprived and eventually went mad with rage. A new medicine was produced to cure the illness but it has a side effect which turned patients into vampires. Later, these vampires were called the "Bloodivores." They are feared by other people and wear a special necklace that sends a signal to the police if a Bloodivore is unable to control their emotions.
Mi Liu is called a "child of hope" — born from a human and a Bloodivore — but when he along with his three friends are vilified for killing all humans in a bank they robbed, they are sentenced to death. Then a strange thing happens where they are thrown into a mysterious place with a lot of unexplainable monsters along with other sentenced-to-death prisoners. A girl greets them and reveals they have been given new collars that are filled with explosives to prevent them from killing other bloodivores. She then announces their mission: to survive.
