Ethan, upon regaining consciousness, wakes up in his home. When he looks out the window, he sees that everything is different from the days he remembered. An extremely silent and empty day is strange, because the place where you live is very busy, so you realize that the city is completely empty, with abandoned cars and deserted streets. That makes him scared. KNOCK KNOCK - there's someone knocking on your door. Do you want to open the door?
