Five Minutes by Maximilian Niemann

5.30

When John and his daughter Mia are attacked by zombies, they manage to escape to their apartment at the last second. But John was injured in the fight against one of the undead. Unsure whether he has been infected, there is only one test he can take: he must remember, because the first symptom is memory loss within five minutes. While the zombie horde tries to break into the apartment, John and Mia are faced with a terrible decision.
