Lentävät luupäät.

Two brothers from Häme discover that they are actually from Karelia. During the celebration of the newfound fact, one of the brothers is bitten by a bug. After seeking medical help from a doctor - who tries to tell the brothers that he is not a doctor of medicine - the doctor decides to trick the boys by convincing them that the insect in question is called Insectum propellatum, also known as the aviation bug, and unless the affected brother learns how to fly, the bite might turn fatal. During their shenanigans, they become acquainted with a robot that runs on booze, two scoundrels, and the beautiful Miss Universe!
