 A famous crooner who s also a cutthroat record producer is doing a radio interview when a songwriter breaks into the studio and accuses the singer of stealing his song, waving a demo record around as proof. The singer smashes the disc and storms out. The interviewer hurriedly cues up some records to cover the dead air. While everybody in the radio station searches for the singer, someone finds him in the music library and shoots him. The singer is found clutching a recording of "Danny Boy," which implicates the songwriter (whose name is Danny). But is it a dying clue or a red herring?
