Nothing Else But Water (2014)

This story takes place in Lisbon at the time of the great maritime discoveries. Explorers, looking like pigs, arrive in the harbor after a long voyage across the oceans. Everywhere in the city small groups gather and congratulate each other. They organize spontaneous round dances and celebrate their return. Meanwhile, a young pig has the strange feeling of being completely isolated from the others in his own native city...
