Robert Bobin has been an assistant accountant for twenty years now and, although meek and obedient, is getting weary of his monotonous, limited life. He tries marriage but, unfortunately, Blanche, the nurse he marries, proves to be a shrew. One day, a miracle happens : Michèle, a young orphan and fellow-worker gradually develops tender feelings for him. But will Robert be able to overcome his mediocrity and grasp this unexpected opportunity to find happiness?
