Suddenly, a significant part of the planet's population was infected with a strange virus. Scientists tried to find a vaccine that could cure all the sick. However, it failed to do so.
The only thing they were interested in was the blood of the living. To achieve it, they went out at night to hunt. As it turned out, daylight is extremely destructive for them. That is why they tried not to leave their shelters during the daytime. But the problem was that gradually the climate on the planet began to change. Because of this, the duration of daylight hours has significantly decreased.
The settlement in which the hero ended up was hidden in a labyrinth. It was guarded by terrible monsters, so it was not possible to escape from there. However, all the guys have to join forces to do this, because it was extremely dangerous to stay here. And the children understood this very well, so they eventually escaped. Miraculously, they managed to get to the base, which, as it turned out, was completely inhabited by people. It turned out that the number of survivors was much more significant than the guys expected.
They planned to stay in this laboratory and help scientists find a way to create an antidote that could cure absolutely everyone infected. However, gradually the heroes come to the conclusion that it is completely unsafe to stay at the base.
