Buenos Aires, 2019. Lucrecia, who jobs as a museum security guard, foresees a sharp rise in the dollar’s value with her pendulum and falls in love with a currency exchange house employee.
A young writer sends secret love letters to her neighbor, whom she spies on her window every day. He reads and collects them until one day, lacking inspiration, he appropriates one of them and sends it to his beloved. From here on, these letters of love, and some other heartbreaking ones, will travel between different characters who will steal each other's words, until they end up halfway around the world.
