there's a zombie apocalypse. one of the zombies bit your hand. the army fights zombies that cannot be healed and catches those that can be healed. Your brother is in the army, he noticed that you are turning (you are 50% zombie), he catches you, he puts something in your mouth so that you don't bite, he locks you in a cage in the truck, he drives you to the laboratory, he drags you behind him, he locks you in cell in the laboratory, clicks something on the tablet by the door and sleeping gas flies into the cell. a scientist enters the cell, ties your hands with a special tourniquet, puts a special drip with a medicine that will help you return to a human form, the scientist came out and approached your brother, told him to keep an eye on you but not to come in and if he turns into a man, he is supposed to free you, but he is to make sure that you don't go away from him.
