The pregnancy of Newcomer Cathy Frankel by her human boyfriend, Matt Sikes, ignites tensions city-wide as extremist groups who fear the implications of the birth of the first half-human/half-Newcomer child threaten Cathy's safety. The danger escalates when the medical facility treating Cathy is attacked, forcing her into seclusion. Meanwhile, George Francisco is drawn into a Newcomer cult headed by a mysterious messianic figure. Obsessed with the cult, George quits the police force to devote all his time to his new religion. Now with his partner gone, Sikes must defend his newborn baby from a hostile band of criminals determined to destroy anyone who's different-- even an innocent child.
