"Charlie Matheson died two years ago in a car accident. So how is a woman bearing a startling resemblance to her claiming to be back from the dead? Detective Mark Nelson is called in to investigate and hear her terrifying account of what she's been through in the afterlife. Every year Detective David Groves receives a birthday card for his son...even though he buried him years ago. His son's murder took everything from him, apart from his belief in the law, even though the killers were never found. This year, though, the card bears a different message: I know who did it."
