Irene is in the later stages of her life and remembers something that happened when she was a very little girl that changed her life forever. In just a few days a secret would be born that she would keep secret from that point onwards, a time divided between the seaside at Granada and her definitive move to Madrid. Her story overlaps with that of Enrique, a lonely old man who abandoned the priesthood and is reluctant to face up to his past. He lives in a big, dilapidated old house in a small town in Soria at the foot of a mountain and feels himself removed from time and place. They are both friends with young friends María and Alonso and with their help they learn that destiny can be elusive and capricious and wrap people's lives in a mysterious and incomprehensible fog. 'Cosmos' follows four parallel lives whose owners have known the privilege of true love.
