It's a race against time to identify the cause of a deadly virus, spreading rapidly and headed straight for the city. It's up to NorBAC to identify patient zero and contain the outbreak. As if a deadly virus wasn't enough, NorBAC's Chief Scientist, David Sandström must deal with the unexpected arrival of his belligerent teenage daughter, Lilith, and arguments with NorBAC's Executive Director Caroline Morrison over the security clearance of the one member of his team he'll need the most, his top virologist.

Lilith befriends Mick, who is dying and desperate for David to help him discover if he really is a clone and possibly save his life. Meanwhile, NorBAC has managed to locate patient zero and must proceed with the interrogations at "Hazmat City." Was this an act of Bioterrism? Caroline is determined to find out who's responsible as more die and one more is exposed. David must now face his fate.
