Aesop is a trouble-making young boy who finds himself in another world filled with creatures he never believed to exist, such as fairies and talking donkeys. He sets off to find a way back to the normal world. On his journey he befriends many classical creatures from well-known fables and encounters many trials, each teaching him a valuable lesson.

An animated film based on one of the renku (collaborative linked poems) in the 1684 collection of the same name by the 17th-century Japanese poet Bashō. The creation of the film followed the traditional collaborative nature of the source material – the visuals for each of the 36 stanzas were independently created by 35 different animators. As well as many Japanese animators, Kawamoto assembled leading names in animation from across the world. Each animator was asked to contribute at least 30 seconds to illustrate their stanza, and most of the sequences are under a minute (Yuriy Norshteyn's, though, is nearly two minutes long).
