Lorina, a young schoolgirl, is led by a black rabbit through a wood to a magical land. There she finds a race of green people, who are all overworked, starving and suffering from the toxic fumes billowing out of a nearby castle. She decides to gain access to the castle for the poor green people, and within its walls she meets the "insiders", selfish creatures who hoard all the resources and treat the outsiders as slaves. Her quest leads her to encounter the bureaurat, the superviper, the farmadillo and, eventually, the awful Piggident himself. Will she be able to save the green people from the cruelty of these "insiders"?
