A children's fantasy comedy about little Lucie, the nasty leader of the boys' party Osvald and two magical characters from the plasticine. Lucie is a six-year-old girl who can't wait to go to school for the first time. And since all her friends are still on holiday, she has no one to play with. Osvald's fifth-grade group doesn't care about little girls. Unless she proves her mettle by shoplifting. Lucie goes to the department store and reaches for a box of plasticine. And this is the beginning of an extraordinary adventure, for out of the box come two magical plasticine figures who become Lucie's mythical friends with whom she will have the most wonderful adventure at the end of the summer. Directly followed by ...a zase ta Lucie! (1984).
