Akin is one of the brightest members of the astronomy club. Having discovered a spaceship that has settled into our orbit, Akın sits on the agenda of the world with this discovery. Hayri also contributed to the discovery, and this allowed him to gain a little fame. An alien, the real owner of the ship, who saw Hayri's photos in the newspapers and caught his attention, decides to find him in order to get him to help him. The alien, who sets out to find his fateful friend, is unaware that he is after a group of people whose intentions are not good at all.

Hayri, the youngest person who went to space, became quite famous and was accepted to the Science and Technology School. He now spends very little time in the neighborhood and spends most of his time on the giant robot Hayrimatör, the “Invention of the Century” as he calls it. Even though he designed and called it as an engineering marvel, Hayri could not manage to obtain the power source to run the Hayrimatör. With the support of our alien hero Zobi, Hayri manages to make the Hayrimatör work, but the villains go after the invention. This time, Rafadan Tayfa will team up to rescue Hayrimatör, who has been driven out of control by the Agent and his men.
