Sam Dalton is at the end of his rope. His daughter, Jessica, lies dying in a hospital bed from a mysterious disease that has her doctors completely baffled. Without being able to identify the disease or its cause, they are unable to devise a cure and can offer Sam little hope. All he is left to do is sit there and watch his little girl wither away, day after day.

Despair has him wrapped tightly in its bony grip when an encounter with an empty-eyed vagrant he dubs the Preacher gives Sam the opportunity he has been searching for, a chance to bring his precious daughter back from the brink of death. He doesn't know who the Preacher is, or if the Preacher is even human, but Sam doesn't care. All he can see is the proverbial light at the end of the tunnel.

If he's strong enough to do what needs to be done.

How far would you go to save someone you love?

Sam Dalton is about to find out.
