Private Investigator Nikki James is in San Francisco at the request of her business partner and best friend, Jake.
His friend's wife is missing, and he is determined to find her.
The authorities believe the kidnapping is the work of a sick mind - Nikki knows it is something much worse.
Vampires. Michael Kelly has returned from a vampire hunting exhibition in his homeland and wants to relax.
When he discovers Nikki's gone to San Francisco he has no choice but to follow - not only to keep her safe from the vampire gang, but because he fears the psychic talents she's beginning to develop.
As the body count begins to rise, so too does the danger.
Soon Nikki becomes a target but she has no intention of obeying Michael's demands that she leave.
She's tired of playing it safe and wants him to realise it's all or nothing...
