After her father, the great chieftain Krok (Ivo Novák) dies, the tribes of the Bohemian forests elect his youngest daughter Libuše (Winter Ave Zoli) as their new ruler.
Together with her two beautiful sisters, the healer Kazi (Veronika Bellová) and the priestess Teta (Vera Filatova) and an army of women under the command of her best friend, the Amazon Vlasta (Lea Mornar), Libuše guides her people with the power of her visionary abilities.
During her reign Libuse envisions the city of Prague at the Vltava river, starts mining in the rich Bohemian mountains and helps her farmers to fight a deadly plague.
When the peaceful community of farmers is under attack by raiders and split into different parties of power hungry landowners under the guidance of their plotting chieftains Domaslav (Pavel Kríz) and Vrsovec (Marek Vašut), Libuše is eventually forced into marriage by her own people.
The English language screenplay by Irish writer/director Lance Daly and director Constantin Werner was based on the 18th and 19th century romantic German fairytales and plays by Johann Karl August Musäus, Clemens Brentano and Franz Grillparzer who emphasize the supernatural elements of the story and combine that with psychology and philosophy, as well as on the 1894 publication Old Bohemian Legends (Staré pověsti české) by Czech author Alois Jirásek.
It is also a passionate love story between two lovers from different social status, a queen and a ploughman, who meet in a time when the old ways of the Slavic tribes were coming to an end.
