In Bath in 1850 a witch is murdered in a ritual granting longevity to four men. What they are not aware of is that she has bestowed the same power to another called Seth to avenge her death. Cara is a descendant of the witch and fills her days with food with her Irish-themed catering business. Her nights are another matter; they are full of erotic dreams of a mysterious lover, or nightmares with mutilated bodies. So this wasn't the best time for her Nana to tell her she is coming into her power. Of the original four immortals, Vincent is the only one left and to stop his own long life from fading he needs another witch to kill. Seth was meant to protect the witch's descendants from a distance, but with Cara he can't stay away. He has to make a choice to love Cara, or avenge the original death and possibly die himself. Cara has the fight of her life on when one man comes to kill her, and another to love her.
