Bébert et l'omnibus

In a bustling department store, while their parents are preoccupied with shopping, Tiennot, more interested in pursuing girls, enlists the help of his younger brother Bébert. On the train journey home, frustration boils over as Tiennot, irritated by Bébert's antics, abandons him in the last car, which unexpectedly detaches and veers off in a different direction. Alarm spreads through the family as they realize Bébert is missing. Meanwhile, the mischievous boy finds refuge with the station master at Verneuil L'Etang, where his antics disrupt the SNCF railway network. A kind-hearted inspector eventually steps in, ensuring Bébert's safe return to his relieved family.
