In the circus tent „Joy” the same thing happens every day – they dismantle and assemble the tent with a dome full of stars, give performances, and move on to the next place. Lynx and parrot trainers quarrel over every little thing, and Valera the clown always performs alone. Until one day a new partner joins him, the clown Yana, and he starts to dream about conquering the world of the circus together with her.
