Torrential rain causes the river to swell, flooding a village. The Crebinsky brothers and their cow miraculously save their lives when they are swept away by the current. They end up somewhere along the coast. That is where they grow up, at the foot of a lighthouse. They survive collecting things that the sea brings: the “crebas”. Completely isolated from the military events that are taking place around them, they create their own world. A peculiar universe full of imaginative realism. The normal rhythm of their lives with Muchka, their cow, is shattered when she disappears. The brothers then start a desperate search that will take them from the coast to the interior.
