The police find the body of hostess Helen Howard (Wanda McKay), disposed of by petty racketeer Nick Mantee (Kane Richmond) after she was shot in his Bluejay night club by Benny Nordick (John Gallaudet) because she knew too much about Mantee's rackets. Police Lieutenant Williams (Conrad Nagel) and police Sergeant Tom Ramey (Ralph Byrd) inform the dead girl's parents and sister Nancy (Audrey Long) of the run-away's death. Nancy, inpatient waiting for the police to get a solid case together, signs with the Mercer Agency operated by Nordick, training girls for an excessive sum which they work off as hostesses at the Bluejay Club. Nancy becomes a hostess at the club and after a party for Latin-American night club owner Barda (Anthony Warde), she uncovers evidence that places Helen at the club. She accuses Nick and Benny of the murder and the two mobsters realize they must do away with her.
