La chanson d'une nuit

Enrico Ferraro (Jan Kiepura), a renowned opera singer, seeks refuge from his demanding manager by escaping to the French Riviera. He meets Koretzky, a man who bears a striking resemblance to him, and hires him as a double. However, complications arise, and Enrico finds himself torn between his genuine connections with Mathilde and his increasingly complicated arrangement with Koretzky.
