The ghost: Anna, played by Jennifer Ehle, is the ghost of a woman who was recently killed in a car accident. Anna ran a free clinic in her lifetime. In death, she retains her good heart and desire to help poor people.
Boo who? Anna appears to her ex-husband Michael, played by Patrick Wilson, and asks him to wrap up her unfinished business and take care of the clinic. Michael is an incredibly talented surgeon, but he's also self-absorbed and cold, and could learn a thing or two from Anna's compassion. Her haunting is more "Touched by an Angel" than "Tales From the Crypt."
