Small time crook Gabriel Kemp is only trying to make a living when a hit-and-run leaves him for dead. Waking up in hospital to an angel at his bedside gives him a second chance, but one that comes with a condition.

Fleeing San Francisco doesn't mean he can evade the deal either – he still manages to meet Abigail Harris, the woman he's promised to protect. He might not believe in the psychic visions she claims to have, but he knows even the chance of her identifying the serial killer terrorizing downtown L.A. puts her in danger.

The only way to keep Abby safe is to find and stop the killer. If that means taking on the devil determined to turn the City of Angels into the City of Hell on Earth, then so be it.
