So Long, and Thanks for All the Fish

In this fourth installment of the famous sci-fi comedy saga, Arthur Dent returns to Earth after years of hitchhiking through the cosmos, only to find the planet completely intact. This is deeply confusing to him, considering he distinctly remembers it being demolished by the Vogons to make way for a hyperspace bypass.
As Arthur tries to rebuild a normal life, he falls in love with a mysterious woman named Fenchurch, who shares a strange connection to the day the world supposedly ended. Together, they embark on a quest to discover what actually happened to the Earth and uncover the final, parting message left behind by the planet’s dolphins before they vanished.
