When the star violinist of the Manhattan Symphony Orchestra is found murdered in her dressing room, Detectives Briscoe and Green don't have to look beyond the concert hall for an array of leads. The priceless violin she played is missing and the rest of the violin section is found to have been resentful of the recent Juilliard graduate's rapid ascent to stardom. Meanwhile, the brilliant and debonair conductor Carl Reger (Ronald Guttman), whose wife also performs in the orchestra, points the detectives toward a stagehand who may have been rebuffed in his advances toward the victim, as his own relationship with his first chair violinist comes under scrutiny.
