The Kid doesn’t know where her parents are. They left with a promise to come back months ago, and now their 17-year-old daughter is stranded on Swan Island. Swan isn’t just any island; it is home to an eccentric old age separatist community who have shunned life on the mainland for a haven which is rapidly sinking into the ocean. The Kids’ arrival threatens to burst the idyllic bubble that the elderly residents have so carefully constructed – an unwelcome reminder of the life they left behind, and one they want rid of.
