“The vice squad trick a foreign embassy into squealing on an infamous gang of crooks.” [3]
A foreign embassy worker is caught, in an embarrassing situation with the wife of an ambassador. The wife panics and kills a policeman. In trying to avoid revealing the name of the ambassadors‘s wife to the police, the embassy attache makes a deal with a dirty cop to be used as a stool pigeon to inform on prostitutes. He ends up working on a case of a girl who he knows is innocent, but being framed by the cops, so he is faced with the difficult decision of exposing his past or letting her go to jail.
