After the shaky beginning of their relationship, all Natalie and Michael want is to settle into life as a married couple. But things haven't been quite the same at the police department since Michael saw his now-wife turn into a werewolf. When he signs on to carry a package to Scotland, the professor who hires him winds up on the floor of his lab in a pool of blood. Natalie soon learns that werewolves aren't the only creatures who roam the night, and those who killed the professor are now hunting for her and Michael. Maybe some of the creatures of the night really are evil.
