He contacts his zoologist brother Alejandro (Castro), who lives in a woodland hut expecting bears to return to the area they inhabited once. Guillermo is forced by his foster mother Josephine (Geraldine Chaplin) to move with Alejandro. Tensions arise as Alejandro's idealistic perspective is in sharp contrast with his brother, Guillermo.
