Košinj and its neighbouring villages, the low-lying areas of Lika, are tormented by floods every twenty years or so due to heavy rains and melting snow. Villages within a couple of kilometres of the River Lika find themselves submerged by water. The entire region becomes one huge lake where the only means of communication is by boat. This film follows the stories of two volunteers one Serbian and one Croatian. When the floodwaters come, they relocate trapped locals and deliver essential supplies – and they are the only remaining link with the rest of the world for their respective communities.
