When New Orleans District Attorney Kirsten Lord and her nine-year-old daughter are imperiled by a chillingly believeable death threat, Lord has no other choice but to accept the Witness Portection Program's offer to hide them in Boulder, Colorado. There, they meet program beteran Carl Luppo, a solitary mob hit man who is tormented by his former life and has nothing but time for regret. Sensing that Lord and her daughter's safety has been compromised, Luppo takes on the role of sentinel, fully realizing this might be his last shot at redemption. While Lord suspects that Luppo's warnings about the program's dark side are for her own protection and that she should believe the former assasssin's instincts, the only person she can really trust is nine years old.
