A Space Fighter Attacks Nobita

Shizuka told a story about her aunt's dream that can predict the future. Everyone got shocked, except Nobita who underestimated it. As Dekisugi told his story, Nobita went home. Complaining to Doraemon, he pulled out the dream prediction candy and explained it. Nobita ate one and slept, dreamed about an alien's spaceship found the earth as a safe planet to live and went to it. Still unbelieving, Nobita slept again and turned out that the aliens will came to Japan. In danger, they call anyone they can, but failed.

Even their friends didn't believe them. They thought Dekisugi would believe them, but he didn't. When their friends making fun of them, Nobita slept again and warn them about radish and Kappa, and it turns out it was real. So, they started to make a plan, and no results 'till the night. Shizuka came to Nobita's house, but found that Nobita didn't went home, yet. Getting hungry, Gian punched Nobita and walk away with Suneo. The alien's spaceship traveled and unfortunately, it entered Shizuka. Having a cold, she went home.

Dinner time, watching TV, bath time, Nobita got worried and he found out that Shizuka got sick. They go check Shizuka to make sure it's not the alien's fault. Doraemon used the doctor's kit and found the alien's spaceship stayed in Shizuka's stomach. Even if they use the ultra super almighty vaccine, the spaceship and the aliens there still survived. Instead, they entered into Shizuka using the teleporting submarine. They still used the vaccine, but in a water gun. The spaceship started to shot Shizuka's stomach wall, making her getting more sick.

They secretly entered the spaceship using the pass loop. Getting caught, they ran away and accidentally, Nobita pressed a button, making them slid down to a large room. The aliens quickly came and cornered them. Then, Nobita slept and getting an idea. Doraemon shot the upper hole using the air cannon and broke the spaceship, making the vaccine flowed into it and vanished all of the aliens. Feeling thankful, Shizuka told Nobita about her dream getting stuck in her meal. It turned out that Nobita got stuck, but in the blankets.
