Post Apocalyptic

It must be difficult to run with a broken leg, especially because you take pain a lot worse than anybody else. So hiding far isn't really an option. Maybe you can hide behind the door when they open it, and you'll be covered.
You limp to the door and when a lady in black comes out, gun ready, she seems confused. Nobody is there. Turning around she begins to walk back inside, and you celebrate. Yes, she didn't see you.
But you celebrate too soon, and she hears a sigh coming from behind the door and checks. There you guys are, standing face to face, and you faint.
