E City was invaded by the virus, and humans turned into "corpse suckers" who were afraid of sunlight but extremely ferocious.
In order to survive, a group of people hid in the Imperial Bank Building, the strongest building in the city.
To ensure safety, the Imperial Bank Building was built into a special building that cannot be entered from anywhere except the gate.
Not even a mouse can do it.
Eleven people who came to this building from all over the world never knew each other, had no grudges, and relied on each other for survival.
But when they woke up one day, their members died one by one. Some people believed that there were corpse suckers mixed into the building.
But some people firmly believe that this is a man-made murder.
In the death incident, some people lost their wives, some lost their lovers, some lost their relatives, some lost their children, some lost their mothers...
They are sad and angry, but facing the current situation of the cruel world, some of them choose to give up, some choose to forget, and some choose to persist in finding the truth.
In a closed space with surveillance cameras everywhere and no free access,
A delinquent girl with a withdrawn and evil personality, an infected person with simple thoughts and violent behavior, a genius girl who cannot express herself in normal language,
A bank president full of wisdom and leadership, a romantic and dedicated sprayer, a selfish and sinister fertilizer dealer,
A kind, ignorant and ignorant doctor,
Who is the murderer among them? What's the motivation? What was the murder weapon? Why do corpses disappear?
And how can we do those things that are closely related to the time of death that humans cannot do?
