Tiago, a tour guide with a broken heart leads Karen, a grieving and aging Brazilian woman, around a Lisbon of strange suicidal heroes. Tiago lives with his father, Raul, an old sailor haunted by historical defeats, and with his son, Manuel, a teenager fantasising of a solitary, but erotic, trip to the cosmos. All together, they take Karen through dreams, lost glories, and catastrophes to meet a fallen hero who disappeared many centuries ago on an island in the South Atlantic Ocean.
