Renowned researcher Jake Foster uncovers a terrifying secret behind Boston's rising infertility rate. Meanwhile, in a nearby ER, his wife, Dr. Brett Foster, unsuccessfully tries to save a young man with no visible injuries from bleeding to death--the fifth such fatality in a week. Working together, Jake and Brett discover that the two epidemics stem from the same diabolical source.
