Via morta

In Portbou, for a few days and by chance, a series of disparate characters converge: a history teacher and her first love, an urbex journalist, a prostitute and a police inspector. At first, these strangers seem to share nothing with each other, but a death, that of one of them, will end up uniting them by force. What is it that takes place in Portbou that ends with one dead and turns the lives of several characters upside down? And most important of all, what role does Le Rayon Vert, a hotel that has been abandoned for years, play in it?
