That September 3, 1939, the day of the Spanish exiles' splendid arrival in Chile, the Second World War broke out in Europe. Victor Dalmau is a young doctor when he is caught up in the Spanish Civil War, a tragedy that leaves his life - and the fate of his country - forever changed. Together with his sister-in-law, the pianist Roser Bruguera, he is forced out of his beloved Barcelona and into exile. When opportunity to seek refuge in Chile arises, they take it, boarding a ship chartered by the poet Pablo Neruda to the promised 'long petal of sea and wine and snow' over the seas. There, they find themselves enmeshed in a rich web of characters who come together in love and tragedy over the course of four generations, destined to witness the battle between freedom and repression as it plays out across the world.
