Aww, this movie is sad... It's about biological weapons going off in Los Angeles and a man sealing up his house to stop the virus getting in. His wife was in the explosion and she's come home and he can't let her into the house. I decided to read what happens and it has an ironic twist because the woman through her phone through the window which let the virus into the house, and because it was so sealed up, it had a chance to multiply and the air in the house was lethal. The guy died... The woman however lived because she was in an open-air environment for the entire movie.
