zombie apocalypse

It was an ordinary day in the city, you and your parents were driving to your grandparents', but suddenly you stopped, apparently there was an accident, but police officers on scooters were already driving past your car, some drivers got out and looked what was going on, your father also got out and heard screams there, your younger brother got scared and hugged his teddy bear, suddenly a man fell from a high-rise building, but he didn't die, but got up and it was as if he was dead and alive, and then he pounced on the man and began to bite and eat him

An unknown virus has triggered a zombie apocalypse.
