S1·E1 The Brothers

Suspended from her normal duty, Officer Kate Benson is recruited by Special Unit Two (SU2) for a temporary assignment. Mature gargoyles that have been hibernating (on churches in Europe) have awoken and are collecting food (people) to feed to their eggs which have been incubating for 17 years. The victims are being kept alive until the eggs hatch. SU2 has 24 hours to track down the gargoyles and destroy the nest before the mass hatching occurs.
