Animales racionales (1983)

A very simplistic parable about humans reduced to savagery filmed on a low budget with no dialogue. Two men and a woman wake up in the aftermath of nuclear armageddon. At first they are innocent and happy and are joined by a helpful dog, but soon hardships, food, pleasure, weapons, and mostly lust convert their simple paradise to hell with jealousy, rage, and greed rearing their ugly heads. Who will the woman choose? The answer is not what you think. An uninteresting but entertaining romp full of sex and nudity.
