A comedy about exchange of 12 apartments , which, its organizer, lawyer Radosta, rightly called Action Ball Lightning. To prepare, organize and execute the exchange of twelve apartments is a work worthy champions. Radosta, who was excellently played by Rudolf Hrušínský, solved all sudden difficulties and complications on the fly and with grace. To be sure that the on the D-day everything goes well he prepares a little rehearsal, which reveals many minor issues caused for example by wedding ordered to inappropriate term or hesitation of some participants. Last but not least a night exercise announced by drunk psychologist Knotků, creates a lot of confusion that nearly sabotaged the whole operation.
