In the heart of Sarreguemines, a pottery town on the Franco-German border...Hugo is living his 15-year-old summer between the train station and the city's industrial wastelands. When he's not on his motorcycle, he masks his lack of confidence by improvising as the leader of his trio of friends. Today, he discovers an authentic gun : it's now or never to prove his worth to the adults in the shopping area. In this world where wheelies, alcohol-laced shisha, and cheap tobacco reign, Hugo will have to carry out a gas station robbery on the other side of the border... without knowing a single word of German!
