A nasty virus has spread across the race turning the people to some thing. . .else. After a brief setup (and a cluttered hitandrun ) we're introduced to an ambulance and its four residents. Sonia (Helene de Fougerolles) and Marco (Francis Renaud) are riding and together two cops. While they head to get a research center called NOAH that working on a treat and is infection free, tensions rise between these, and situation lead to Marco and Sonia holing up in an abandoned construction. She is pregnant, inlove, and apparently immune to the virus... and she understands that he's been infected. He slowly transforms but her love refuses to offer up on a treat, so she sets out to survive attacks from marauders, the onslaught of infected, and the threat from the father of her baby.
