Vous n'avez rien à déclarer? Banda sonora (1937) BSO

A shy young man, Edmond, marries Paulette, the daughter of his employer, Jules Papillot. The bride is beautiful and the prospects are good. But there is a little hitch: the young husband is unable to fulfill his conjugal duties. All this because of a customs officer who had the really bad idea to ask him "Anything to declare" at the precise instant when, on the train, he was about to embrace Paulette. Papillot, alarmed by the situation, decides to help his son-in-law : psychiatrists, loose women to awaken his libido again, anything goes. Luckily - although following plenty of ups and downs - all is well that ends well.
