On a large island, somewhere in the middle of the ocean, humans are living an ideal life, peaceful and equalitarian. The price of their tranquility: Michels, little creatures carrying out the work that the humans no longer want to do. Every year, the Michels are allowed to retreat to the Great Mudpool, a seaside resort for Michels where, in reality, they are killed, crushed and recycled into new Michels ready for use. One day, a Michel escapes from the Great Mudpool and is adopted by a family in the village. His adoption will have a cascading effect on social organisation, confronting the inhabitants with their privileged lifestyle and forcing them to show their true selves.
