Vacation follows a protagonist road-tripping home from college. A sudden volcanic eruption totals his car and destroys all his possessions. Barely surviving, our destitute star builds a life for himself out of furniture that has washed up on the shore, making an unremarkable patch of beach his home. An absurd fable on the nature of nature unfolds as he meets three animal companions: an intransigent seagull, a brilliant spider hidden in a broken laptop, and a divorced fish battling for custody over her 50,000 children.
