There was a boy named Marlin who loved science fiction. He would always read books about science fiction. One day, while he was feeding a stray dog named Poppy, a UFO in the shape of a flying saucer came out of nowhere. It circled above Marlin. One minute later, the flying saucer shot out a beam of light and lifted him inside the saucer. Poppy started barking, begging the saucer to leave his friend alone. But it was too late, and the flying saucer flew away.

When Marlin opened his eyes, he saw a big corridor. He was sucked up again by a giant vacuum into a room where a man was sitting in front of a big table covered in buttons. The man got up and said "Hello" to Marlin. Marlin, in a shaky voice, said "Who are you?" The man said, "I am Umi, and I welcome you to my ship. I am the Commander. Let me show you around." He took Marlin to a strange room where human bodies were stuck to a red wall. "Welcome to my Alienator," he said, and stuck Marlin to the wall. "Have a toasty time. Goodbye." Marlin started screaming. After ten days, he turned into an alien. When he looked into the mirror, he had tentacles in his hair and all over his body, and he had lost his memory.

He was then taken to a strange green planet called Helia. There, Marlin saw aliens just like him. He was taken to a place where he saw names in tiny boxes on a big shelf. His name was taken out by a machine and replaced with "Ryan."

Two years later, a team of astronauts from NASA came to Helia to find Marlin. They asked Umi, "Where is Marlin?" Umi brought Marlin to the astronauts, who were shocked to see him. They fought Umi with space guns and space cannons, and two days later, the astronauts won the fight. Umi put Marlin back on the red wall, and he turned back into a human. The astronauts took him aboard their spaceship, and Marlin came back to Earth. Poppy was overjoyed.
