The Bontemps family, like all the inhabitants of the village of Coussy la Chapelle, are passionate about radio. Coco, the fiancé of Jacqueline Bontemps, participates in all the contests and under the name of Mr. Bontemps wins a beautiful Sunday. All arrive in Paris and in the premises of the Parisian Post Office attend popular broadcasts.
