A biology researcher, living with his family trying to leave peacefully. A remote area where everything is almost fine, almost calm. Then everything changed when an illness spread, people with bite wounds started to caught high fever. Then they were turned to something different than their usual self. They attacked other citizens, turning them into one of the attacker.
It was an illness nothing like they have faced before, and when the researcher found an antidote that almost ready, he found that his city had turned into one hell on the planet. He fought their once fellows, with his sons, and he watched with despair as three of his sons fallen, and he burned them to prevent them from being like other creatures. His oldest son, out of misery for the loss of his brothers, injected himself with the antidote, which burned his face and chest by its side effect. He fought the creatures they called as zombie. He was hurt but he did dot get the fever, for his body temperature was higher than any fever known. He was able to keep his mind, but his body changed into one of the zombies.
Meanwhile the researcher, with the help of his doctor son, found a way to prevent the burning of the flesh. Soon the four brothers tried to fight their way out of the city, along with their father. But out of nowhere a zombie jumped to their car and dragged their father away.
There’s no way to retreat and they were in the middle of the city of the fallen, they had no choice but using the serum. The three brothers injected themselves while the eldest brother fight for their father’s live, but they were too late. When they joined the fight, they found that their father shot himself in the head to prevent himself turned into zombies.
That was the last time for them being human. From that time, they call themselves as Brotherhood.
They fight for each other.
They kill for each other.
For their sake. For brotherhood’s sake.
