A virus has spread across the race turning the people. . .else. After a short setup (and a cluttered hit and run) we're introduced into an ambulance and its four residents. Sonia (Helene de Fougerolles) and Marco (Francis Renaud) are together and riding two cops. While they head to get a research facility called NOAH which working on a cure and is allegedly infection-free, tensions rise between them, and situation result in Sonia and Marco holing up independently in an abandoned construction. She is pregnant, in love, and apparently immune to the herpes virus... and she understands that he's been infected. He transforms but her love refuses to offer up on a cure, so she sets out to survive attacks from marauders the onslaught of infected, as well as also the threat from her baby's daddy.
