A young woman goes undercover to gather evidence to free her boyfriend, an attorney who has been framed for a murder he didn't commit.

What is worse for a defender of justice than to find oneself charged and tried for murder and condemned to be executed? This is what happens to brilliant young lawyer David Rolfe, who has hitherto managed to rid the Big Apple of most of its scum of mobsters and racketeers. Of course taking it out on gangsters was not the best way to please them and after Rolfe arrested Morgan, an underling of powerful gangster Harry Evans, the latter, aided by his moll Claire Foster, succeeded in having Rolfe wrongly accused of the murder of his own cousin, Phil Long. Men are such fools--agreed--but don't forget the wiser sex. Indeed David Rolfe has a girlfriend, society girl Margaret Hughes, who decides to go undercover, posing as a woman of easy virtue, to find out the evidence of her lover's innocence.—Guy Bellinger
