this autobiographical character study of real life new york city detective eddie egan and who also serve a technical adviser for the film and be definitely underrated . robert duvall give a convincing performance a eddie ryan and who suspend from the force after kill a drug runner . that still doesn not stop him from clean the street up from gang and other lowlife scum . the production value be surprisingly good for a little known movie and it include a lengthy car chase in which duvall commandeer a city bus to evade bad guy drive all sort of vehicle . i be lucky to have tap this onto dvd r from turner classic movie and since it probably would not be release on dvd anytime soon .
