The First World War has just broken out when a group of young people find themselves in the port of Barcelona, in anticipation of landing on a ship that will not arrive. Carl is an architect of the well-to-do family, who understands that he's trapped and is seeking a way out; Gloria is a syndicalist, whose head is full of lofty ideals; Sebastian and his wife Catherine are young farmers; Cinto is an unscrupulous rogue who does not know any boundaries, and Mary dreams of becoming the queen of «music hall». For one night only a friendship between them is born that will last throughout the war, but for Carl and Gloria, friendship soon turns into a passionate love that catches them both by surprise and shakes them to the roots. But the differences and hostilities between their worlds are insurmountable. Carl's father is a prominent Catalan politician, while Gloria's father is an anarchist who was convicted of assault on public order and sentenced to death. The delicate balance of society hangs on a thread, but hopes for a bright future still warm the hearts of people to the last. During these turbulent years marked by intrigue and war, only young lovers dare to dream of a better future, but Carl and Gloria soon discover that they will have to pay a high price for happiness.
