Cretinetti is about to get married and he could not be any happier and more in love with his Junoesque consort. But just on the day of his wedding, he reads a notice on the wall explaining how to behave in the case of an enemy air raid. The fear that grips him makes him even too literal in implementing safety indications, causing trouble and accidents that will not only stop him from enjoying his first marital night, but will even cause the collapse of the whole house. In the end, the gendarmes go to him with a conscription notice and take him away under coercion, under the appalled gaze of his new bride.
