In California, two children die of a disease thought to be nonexistent in the United States. Hours later, thoroughbreds at the Churchill Downs are dying of an unidentified virus. Called in to shed light on these enigmas, virologist Jack Bryne discovers that the two events are not only connected, they are deliberate acts of bioterrorism. Moreover, the deaths bear uncanny similarities to the Fifth and Sixth Plagues described in Exodus.
