In turn-of-the-century Budapest, teenage gangs the Paul Street Boys and the Red Shirts have been skirmishing over a vacant lot. When the Red Shirts decide to drive the Paul Street Boys out, they appoint small, sickly Nemescek to spy on their opponents.

The family consists of Géza, the father, a comical and inept figure, his wife Paula who actually dominates family affairs, pubertal daughter Kriszta and 12-year-old son Aladár, a child prodigy. The cat Maffia and a dog, Blöki accompany the family. Dr. Máris, their cynical neighbour, is regularly and unvoluntarily involved in disasters surrounding the family.

Every night Aladár visits a different inhabited planet using an inflatable interstellar cosmic ship with his talking dog Blöki.

Geza Mezga, Paula, teenager Kriszta their daughter and the restless little child, Aladar. So they are the Mezga family. Maybe Maris neighbour should also be counted here. They are always embroiled in extremely strange adventures, thanks to their "distant" relative, MZ/X discovered by Aladar. With the help of Aladar's own radio transceiver, they get in touch with their thirtieth-century relative. Incredible things happen suddenly in an otherwise ordinary family.
