In Basque country, feuds, governments, and wars come and go, while cows placidly observe the strange behaviors of the humans who care for them. In 1875, during a massacre inspired by an out-of-control family feud, a farmer and his friend find themselves in a ditch together. One of them dies, and the other survives by playing possum using his friend's blood as a disguise. As the film flashes forward in time, the man is now a grandfather who amuses himself by painting the tranquil gaze of cows over and over again, while he observes that his son is having an affair with his dead friend's granddaughter. Finally, during the Civil War in 1936, violence again mars the life of the family, as the illegitimate son of the earlier affair attempts to make headway with his life.
