Peter Cammon, now retired from New Scotland Yard, is drawn into the suburbs of Salt Lake City, Utah, chasing a depraved man who may have deep terrorist connections. Peter is shocked to discover a link to the Unabomber and Oklahoma City bombing cases, files Peter worked on during the '90s. In order to trap the killer-terrorist, Peter and his acquaintance in local law enforcement, Henry Pastern, must strike unholy alliances with corrupt cops, Mexican drug lords and the Unabomber himself. Will Peter have to embrace the rules of the Old West to stop this psychopath?
