A group of students, including a careless but talented student, are preparing for exams. However, their preparations are interrupted by a sudden crisis: an alien gang has landed on the moon and is mocking Earth's civilization. The United Nations decides to send an international space landing to the moon to defend Earth's honor.
The students, along with a group of misfits, embark on a mission to the moon. Upon arrival, they discover that the aliens are actually intergalactic hijackers who plan to steal the moon by changing its magnetic field. The students and their allies try to stop the hijackers, but they are initially unsuccessful.
However, just as the hijackers are about to succeed, the students come up with a plan to use special equipment to defeat them. The plan works, and the hijackers are thwarted. The moon is saved, and the students return to Earth as heroes.
The story also involves a subplot about oil, with one of the characters, Kuzya, becoming an oil tycoon after discovering oil on the moon. The story ends with the students returning to their normal lives, but with a newfound sense of purpose and accomplishment.
