Manuel Muñoz Rivas : manantial
After undergoing complex neurosurgery and a long hospital stay, an elderly man, now partially rehabilitated, goes on a weekend excursion with his wife. Together they travel by car from the mouth of a river to the mountains, where they continue on foot, in search of the remote source of the river. The route is confusing and will test both their physical and moral stamina. When they finally near the spring, they are surprised by nightfall before they can see it with their own eyes.
