There is a tradition of crazy comedy in France, and this one is almost handy. The plot alone was so bumpy that male and female spies went to study opera and wanted to spy on the top-secret information that widow students might have, only to find that the opera class was like a spy concentration camp, coveting widows. Behind the big big lungs, there is actually talking about music, modern lust, and innocence. All the characters are in a race against time, the widow's singer dream comes too late, the female spy hates the time has passed, the dancer chases the tail of his youth, only the male spy is like the vicissitudes of breakfast. The singing class is like a place for great physical and mental liberation, the sex portrayal is bold and alert to Bai Rui, and the plot develops freely and creates its own style.
