The squad members investigate the attempted rape of a female barrister who was apparently saved by a vampire. They find that she has been desperately trying to have a child, and has been been impregnated in-vitro with her late husband's sperm, but the pregnancy is not normal. Meanwhile, Jack has disappeared without trace and Kirsty tries to get Jacob, a journalist, interested in investigating his disappearance.

After a boy kills a priest, the squad discovers vampirism among the schoolboys, even though none of them appear to have been bitten.

The squad becomes interested in a shipment of mysterious crates of medical supplies from Brazil.

The captive vampire is identified and the squad discovers a vampire plan to exterminate mankind. Meanwhile, Michael searches for Kristy, who seems to have been abducted.
