Everything started with an unexpected meteor shower. Among the burning hot meteors, there were four tiny spaceships. Suddenly, under the influence of a mysterious force, the meteors changed their direction and made a right turn. It seemed that their destination was a blue sphere not far away - Earth. In Michigan, there was a quiet and comfortable family where Mr. Stuart Pearson and his wife Nina lived. They had three children: Hannah who was years old, Tom who was years old, and their eldest daughter Bissenerai who had just fallen in love. The entire family decided to relax and planned to go out for a few days. They packed their belongings and came to a vacation cabin in Maine. With them were Uncle Knight, his son Jack, dear Nana Rose aunt, and the twins Art and Li. However, Bissenerai's boyfriend Richie showed up uninvited, making the travel group much larger.
In the evening, a strange cloud surrounded the vacation cabin. Lightning flashed and thunder roared. Suddenly, a strange object landed directly on the roof. Then, four aliens descended from the spaceship. They were the ship's technician Skip, the fearless captain Tessar, the muscular Riser, and the only female member Spex. These extraterrestrial creatures came from a distant planet. Their superpower was to use advanced technology to control people's thoughts. The careless Richie unfortunately became a puppet under the alien's control. With Richie's help, the aliens captured several children, but Tom and Jack managed to escape.
Not long after, these children discovered that the aliens' mind control only worked on adults and was powerless against children. This gave the children the chance to challenge these unwelcome visitors. They used their ingenuity to create many strange toy weapons and fought against the aliens. The unaware adults didn't know what happened; they just thought that children liked to play around.
During this time, a touching friendship developed between Hannah and Spex. As the only female, Spex had no interest in fighting. She just wanted to go home. This alien with four arms and four hands was gentle at heart and loved peace. In her friendship with the children, she gradually hoped to put an end to the war with her own efforts. So she joined the human side and fought alongside the children. The battle continued, and laughter echoed. Perhaps these aliens did not come to destroy the Earth. They might just be messengers.
