One evening, after the mother went to dance class, two grandfathers come to take care of the three grandchildren: the serious Juozas and the cheerful Juozukas. Both grandfathers have different views on their "responsibilities", but soon they are both drawn into the children's fantasy world. Then an ordinary house turns into a magical, sometimes even scary place where characters from different fairy tales gather.

Children will easily recognize situations and characters from such well-known fairy tales as "The Queen of the Spruce Snakes", "Twelve Brothers Flying with Blackbirds", "The Sky is Falling", "How a Man Tricked the Devil", "Three Brothers", "The Flying Ship", "Luckman". ".

At the center of the colorful, inventive and spectacular performance is the youngest grandson Modest, who experiences many trials and adventures that evening. When the mother returns home, she finds not only an "upside down" house, but also a friendly family. And for young Modest, it finally becomes clear that not only in fairy tales, but also in everyday life, it is not the happy ending that matters, but the knowledge that family unity is the strength that will always help to overcome the greatest enemies and fears.
