Return to an Unfamiliar Earth
Arthur Dent wakes in his old bed, in his old house, on Earth, eight years after he saw its demolition by the Vogons. He struggles to believe this reality given his vivid memories of interstellar travel, aliens, and the end of the world. Everything seems normal, yet subtly wrong. He finds his house exactly as he left it, but there's an inexplicable new motorway outside. He consults a psychiatrist, Dr. Emil Blixt, who suggests Arthur's experiences were a delusion. Arthur tries to live a normal life, buying a new car and trying to ignore the nagging feeling that something is amiss. His past adventures feel like a dream, yet too real to dismiss.
The Mysterious Fishbowl and Fenchurch
Arthur receives a mysterious gift: a fishbowl containing a towel and the inscription 'So Long, and Thanks for All the Fish.' This phrase, a known farewell from the dolphins, deeply unsettles him. While driving, he spots a woman, Fenchurch, hovering above the ground. Intrigued, Arthur follows her home. He learns that Fenchurch also has a strange connection to the number forty-two and a feeling of loss, from a global depression eight years prior, precisely when Earth was destroyed in Arthur's memory. They bond over their shared sense of displacement and the inexplicable nature of their lives, leading to a romance.
The Missing Dolphins and the Guide
Arthur and Fenchurch investigate the sudden disappearance of all dolphins from Earth's oceans. They visit a research facility where scientists are baffled by the mass exodus. During their investigation, Arthur discovers his battered, electronic copy of *The Hitchhiker's Guide to the Galaxy* in his plastic shopping bag, confirming his past adventures were real. This discovery solidifies his belief that something extraordinary is happening and that Fenchurch might hold a key to understanding it. The Guide's reappearance also brings back memories of his friends, particularly Ford Prefect, and the absurdity of his previous life.
Finding a Ship and a Robot
Convinced that the Earth he's on is not the original, Arthur decides they need to leave to find answers. He and Fenchurch search for a spaceship. They eventually find one in a field in Norfolk, disguised as a normal house. Inside, they discover a giant, depressed robot named Marvin, who is waiting for them. Marvin reveals he has been waiting for Arthur for a very long time, further cementing the idea that Arthur's return to Earth was not random. Marvin's presence, though still melancholic, provides a way to escape and a connection to Arthur's past space travels.
The Search for God's Final Message
Marvin tells Arthur and Fenchurch that they are to travel to the planet Krikkit to find 'God's Final Message to His Creation.' This message is rumored to be inscribed on a planet called Hawalius, surrounded by souvenir shops. Their journey in Marvin's ship takes them across vast stretches of space. Arthur is excited by the prospect of finally understanding the universe, while Fenchurch, though initially apprehensive, is eager to uncover the truth behind her own strange experiences and the collective memory of the world's depression.
Reunion with Ford Prefect
During their journey, Arthur and Fenchurch land on a space station. There, Arthur is reunited with Ford Prefect, who is, as usual, trying to get a free ride and a drink. Ford is surprised to see Arthur, believing him to be dead. He explains that the Earth Arthur is on is indeed a replacement, created by the dolphins, and confirms the reality of Arthur's past adventures. Ford, having acquired the complete works of Shakespeare for a large sum, is trying to sell them, unaware that they are common knowledge throughout the galaxy. Their reunion is chaotic but comforting for Arthur, providing another link to his real past.
The Planet Hawalius
Arthur, Fenchurch, Ford, and Marvin finally arrive at the planet Hawalius. The planet is a tourist trap, with souvenir stalls and vendors selling merchandise related to God's Final Message. The message itself is displayed on a giant, unadorned rock. The commercialization of such a revelation strikes Arthur as absurd and typical of the universe's general indifference. Fenchurch feels a growing sense of anticipation, hoping this message will provide the answers she has long sought about her own existence and the peculiar state of her Earth.
The Final Message Revealed
As they approach the rock on Hawalius, God's Final Message is finally revealed. It consists of only two words: 'WE APOLOGISE.' This short, enigmatic message leaves the characters, especially Arthur and Fenchurch, in deep thought. It offers no grand cosmic explanation, no complex theology, but rather a simple, almost dismissive, apology. Arthur finds it both underwhelming and strangely fitting for the universe he knows. Fenchurch, though perhaps expecting more, finds a sense of closure in its stark honesty, realizing that some questions simply don't have the answers one expects.
The Dolphins' Explanation
Ford explains to Arthur and Fenchurch that the dolphins, knowing of the impending Vogon destruction of Earth, had created a hyperspace bypass around the planet, saving a segment of humanity. They then built a new, replica Earth for these survivors, complete with implanted memories to minimize trauma. This new Earth is the one Arthur and Fenchurch inhabit. The dolphins' farewell, 'So Long, and Thanks for All the Fish,' was their final message before leaving. Their plan was to allow humanity to continue, albeit on a slightly altered timeline, and to protect them from further cosmic absurdities.
Fenchurch's Departure
After the revelation of God's Final Message and the dolphins' actions, Fenchurch feels a deep connection to the dolphins and their purpose. She decides to join them, believing that her place is among those who understand the true nature of Earth's existence. With a farewell to Arthur, Fenchurch leaves with the dolphins, flying off into the cosmos. Arthur is left alone once more, heartbroken but also understanding. Her departure signifies her finding her own truth and purpose, leaving Arthur to continue his own journey, changed by their brief but deep connection.
Arthur's Continued Wanderings
Arthur is left on the planet Hawalius, reunited with Ford and Marvin, but without Fenchurch. The universe remains as absurd and inexplicable as ever. He is once again a wanderer, but now with a deeper understanding of the Earth he left and the one he returned to. The experience with Fenchurch and the discovery of God's Final Message have given him a new perspective, even if they haven't provided definitive answers. He continues his journey with Ford and Marvin, still searching for meaning in a cosmos that constantly defies logic, but now carrying the memory and wonder of his love for Fenchurch.
