When three of their four children are diagnosed with retinitis pigmentosa, an incurable genetic disease that slowly destroys sight, Montreal parents Edith Lemay and Sébastien Pelletier make a bold decision. Instead of waiting, they take Mia, Léo, Colin and Laurent on a long journey around the world, so the children can see as many landscapes, animals, cities and people as possible while they still have their vision. The film follows the family across several countries, mixing adventure with the difficult conversations the parents must have about what lies ahead. It is a portrait of a family trying to prepare for an uncertain future without letting the diagnosis define their present.
