he Horatio Alger parable gets the film noir treatment with the redoubtable Edmund O’Brien as a whip-smart telephone technician who moves up the ladder of a Syndicate gambling empire in Southern California until distracted by an inconveniently married Joanne Dru and his own greed. Ripped from the headlines of the 1950 Kevaufer Organized Crime Hearings, this fast-moving picture is laden with location sequences shot in Los Angeles, the Hoover Dam and Palm Springs including the famous Doll House watering hole on North Palm Canyon Drive!
