Sarah is surprised by a loud boom noise. All of a sudden she starts coughing and realizes she needs her gas mask. But, it may be too late. She puts it on and breathes heavily and loudly and she fogs up the mask. After a while her breath gets more shallow and she feels weak. She starts coughing again inside the mask. Maybe this is the end.
