Catherine “Cat” Chandler (Kristin Kreuk) is a smart, no-nonsense homicide detective, who is haunted by her own tragic past. When she was a teenager, Cat witnessed the murder of her mother at the hands of two gunmen. Cat would have been killed too, but someone – or something – saved her. No one has ever believed her, but she knows it wasn’t an animal that attacked the assassins…though it was strange and terrifying, it was human.
