Contagion

Beth Emhoff (Gwenyth Paltrow) returns from a business trip to Hong Kong with a stop over at the Chicago airport, where she has sex with her former lover. Beth feels ill, but thinks the problem is jet leg. She travels back home to Minneapolis and spreads the virus to her son Clark and her husband, Mitch. When Beth and Clark die, Mitch goes in quarantine where the doctors realise he is immune to the mysterious virus. Meanwhile in Hong Kong, London and in a small province, cases of the mystery illness are cropping up, as the American CDC and the World Health Organization give their best effort researching the virus. A race against the clock begins, as the virus is spreading in a geometric progression, and if no solution is found - very fast - humanity will cease to be.
