The Belgian linguistics professor Matthias is going through a difficult period in relations with his girlfriend Anne. She is French, he is Belgian, and, oddly enough for an enlightened Europe and a doubly enlightened university environment, this small difference is a shadow on the couple’s personal life. One day, during a train ride, Anne disappears and Mathias goes looking for her in an unknown city.

This picture is a mixture of musical, adventure, science fiction and comedy with the popular singer Bobbejaan Schoepen and several famous Flemish actors.
