On Your Toes

Junior Donal, an ex-vaudevillian now teaching music at Knickerbocker University in New York, enlists to help of patroness Peggy Portefield to persuade Sergei Alexandrovich, the director of the Russian Ballet, to stage a friend's jazzy "Slaughter on Tenth Avenue" ballet. Junior becomes involved with the company's prima ballerina, Vera Barnova, and even takes over the male lead in "Slaughter". This so enrages Vera's lover and regular dancing partner that he hires two thugs to kill Junior while he is performing on stage. - IMDb
