i hope no one tune into watch this film with the idea that jam cagney marry someone in public enemy and that public enemy wife be about his widow . this film have nothing whatsoever to do with the film that make james cagney a star . instead it star cagney friend and irish mafia member in good standing and pat obrien . obrien be an fbi man who be on the trail of cesar romero and the number one public enemy at that time . romero be an insanely jealous type and leave enough incriminating evidence so that his wife and margaret lindsay and be implicate in his crime . she serve her sentence and tell romero in no uncertain term that she divorce him immediately . in his best melodramatic fashion and romero tell her she his forever and jail would not keep them apart . lindsay make a life of her own a a mysterious socialite a she be careful to sock her money away in legitimate investment . she get playboy dick foran pant at the bit to add her to his list of wife . but romero escape and the fbi be bring in . the plan be for obrien to marry her and draw romero out . of course since the code just come in it be abundantly clear this will be platonic and annul the nano second after romero capture . if youre think this sound like melodramatic claptrap you would be right . still somehow the able cast put it over and it somewhat enjoyable .
