Mézga család

Aladár converts an old radio into a transceiver, and with the help of this he manages to contact MZ/X, who is none other than Öcsi, the 125-year-old great-grandson of Géza Mézga from the 30th century. While preparing for his high school graduation exam (80 primary and 40 secondary school are compulsory in their country), he stumbles upon his ancestors from the 20th century with the help of the time-dilation device. Géza is in big trouble, his television has broken down, and he seizes this great opportunity and asks Öcsi for help.

Géza goes fishing, but fails to catch a fish. Paula, who has already invited guests for dinner, is overcome by collapse and shame. Help comes from none other than Öcsi, a 30th century relative, who sends superfoods by light mail. The hyperultra extract is extremely tasty and nutritious, with a shelf life of 300 years. But one tablet contains 1 week's worth of food. This may cause some problems.

The Mézga family goes on a camping trip to Baranyaberenye. However, the motorbike cannot fit all the luggage. They get Máris's neighbor's party car as a trailer. Yes, but it also starts to rain. Öcsi needs help here, who sends a weather control device (meteoro-muto-motor) to Géza with authorization from the space authority. However, manipulating the weather comes with serious responsibility and consequences.
