In a dreamy, dystopian world, a solitary robotic figure can be seen loping through the floodwaters of a former zoo - caring for the few remaining animals left stranded on shrinking island sanctuaries. There are no other signs of life, just the decaying remnants of former civilisation. The robot cares for the animals, feeds them, and eventually builds an ark to sail them away from the rising tide.  

When a storm wrecks their boat, they are stranded on a barren island and all hope seems lost. But when a new robot appears in a hot air balloon, the bedraggled troupe may have a chance for salvation after all.
