The Mézga family is getting ready for a wedding in the countryside, but the car won't start. Who else would Géza turn to than MZ/X, or Öcsi. The new engine from the 30th century, arriving by light post, can do wonders, turning the old, dilapidated car into a real three-wheeled vehicle. They race through the country, on land, in the air and on water, and eventually even manage to run over the wedding party.
