Guillaume Dodut, station master of Puget-sur-Var, learns that the stop of the passenger train will be removed. He then remembers that even the "Côte d'Argent" which came from Paris stopped in its station, that his son stood in front of a very beautiful wagon and said to him "by car for Biarritz". Charles is now 25 years old and completed his engineering studies with an internship in London. He will find his father's station in the second category. After a whirlwind trip to London where he cannot even see his son, Guillaume learns on his return that he is arriving the next day. Little Thérèse, who works at the counter, will even be invited to the family table, because he wants her son to marry the "little one". But Charles had other plans in mind and put the little station in turmoil when he announced that he would live in London and that he would marry Marjorie, the daughter of his boss
