A biologist, Guillermo (Camara) returns to his native Spain after discovering a plant growing in the Antarctic ice. The signs are that he is ready to give up his planet-saving cause. He contacts his wildlife-photographer brother, Alejandro (Castro), who lives in a woodland hut with an enthusiastic young Californian, Vincent (Jesse Johnson), both hoping that the bears that once inhabited this area of Spain will eventually return.
