On the rooftop of a city skyscraper, Detective Hollis (Terrence Howard - Iron Man) pleads with Gavin (Charlie Hunnam - Sons of Anarchy) not to jump. What he does not know is that Gavin, an atheist, is involved in a deadly feud with Joe (Patrick Wilson - Watchmen), a Christian extremist. Joe's gorgeous wife, Shana (Liv Tyler - The Incredible Hulk) is caught in the middle as Joe seeks to test Gavin's faith...or lack of it. Cutting between the present and the past, tension escalates as verbal shots give way to deadly threats in a race against time that no-one can stop.
