Fitting in with normal human society continues to present shared challenges for urbane vampire Mitchell (Aidan Turner) and his flatmates, the earnest young werewolf George (Russell Tovey) and the agoraphobic yet lovely spook Annie (Lenora Crichlow). As the show's third series gets underway, George is arrested just before a full moon, while Mitchell is drawn into a desperate and dangerous attempt to save Annie from permanent exile in purgatory.
