Pretty Aninka is terribly lazy, she just wants to sleep, her mother tries in vain to get her to do any work. Even Toník, her boyfriend, cannot convince her that she cannot just lie in her blankets all the time. There is a storm coming, everyone is trying to get hay under the roof, but Aninka is lying under a tree and would rather go to the Thunderclaps than toil here. And that morning the Thunderclaps took her to their heavenly chamber. There the poor girl has to serve them. One of them, Tlučhrom, even wants to marry her. But Toník, her sweetheart, and his mother search for her all over the world and with the help of good people they even get to the Thunderclaps' kingdom. The cooper hid them in the barrels that the Thunderclaps had come for so that they could roll them around the sky in joy. It won't take them much trouble to outwit the stupid hulks and get Aninka back among the people. And now that Aninka was in her wedding dress, she could go to the altar with Toník.
