In the night, at the top of a big clock, three little automatons come to life in turn: an agile monkey, a pretty dancer and an acrobatic jester, driven by clever mechanisms. Nina, the clockmaker's little girl, begins to dream. She is a little street singer. And a ballerina in love with a little tin soldier. And a princess in search of her beautiful knight lost in the enchanted forest. From burglary to castle attack, from mermaid to dragon, the adventure never stops... like the hands of a clock.
