Mary Hendricks lives a sedentary life in her declining years. A large, black German Shepherd, takes up residence with her - at least from dawn to dusk. She call it Albert. A caregiver becomes friends with the dog after some initial hesitation. Her son never learns to like the monster. When Mary has a heart attack and collapses on her front porch, someone calls 911. She wakes up in the hospital. That afternoon a doctor walks into her room and announces that he is Albert. He's a vampire who offers her longevity. It's up to her. But it's an all or nothing choice.
