The Dam Keeper

In a desolate future, one small town has survived because of a large windmill dam that acts as a fan to keep out pollution. The dam's operator, Pig, works tirelessly to keep the sails spinning and protect the town, despite abuse from classmates and an indifferent public. When a new student, Fox, joins his class, nothing will be the same again - for in her sketchbook, she draws mocking caricatures of classmates, including Pig, but soon learns to use art as a way out of her own darkness.
