Victimes de dénonciations faites à la Gestapo, des résistants belges sont arrêtés et internés dans un camp de prisonniers. Certains d'entre eux occupent la « baraque n° 1 ».

Une bande de trafiquants cherche à s'infiltrer parmi des passeurs à la frontière franco-belge. Josée, une fille superbe, est la maîtresse de Gueule en or, un des contrebandiers.

Life could be so sweet for Gus Vermeulen and Achille Mironval. They are partners in a cheese trade and business is good. So what they plan to do is to marry their two children so as to perpetuate this blissful situation. However two annoying facts cast a shadow over their happiness. Jean-Pierre Mironval, Achille's son, won't hear of anything connected with cheese and would rather be a jazz band leader and Gus, with his passion for spiritism, sows the seeds of discord between the two men. But all is well that ends well.
