The day begins for father and daughter. They climb beyond their treehouse, glide over and under water, cross blooming landscapes, travel through the air and fly on into space. By ship, bicycle, balloon or on foot. A film about travelling, collecting souvenirs in passing and the question of what’s left at the end of a life.

The Smortlybacks are peaceful, fantastic-looking creatures, riding through the desert with the leader of their pack: no water, no shrub, no tree in sight! They are all desperate because their water supplies are running out. After a while they reach the shore of a vast sea. A mysterious creature and their magic fish help them cross the ocean.
