Raimund Gregorious - Mundus, as his students affectionately call him - is a predictable character. A bookish Latin professor, well-respected but perhaps a little boring. One stormy morning, he encounters a beautiful, distraught Portuguese woman in a red leather coat... Later that day Raimund will realise: that moment changed everything.

All of a sudden, nothing in his life feels right. His restlessness is further fuelled when he finds a book by a little-known Portuguese writer, Amadeo de Prado. The appearance of the mysterious woman, and Prado's prescient words, all seem to tell him the same thing: that he must leave everything behind.

So, early the next morning, he packs a bag and boards the night train to Lisbon on a restless journey across Europe and deep within himself in the hope of discovering someone who will make him feel alive and connected to himself and the world once more.
