In 1547, young knight Petr Pětipeský is sent to the remote village of Urbach to oversee the construction of a bridge that promises access to ‘hidden mineral’ wealth. When his beloved Alma vanishes under mysterious circumstances, Petr defies local superstition and ventures into the shadowy workshops of Fichtelberg Mountain. There, he confronts strange figures and uncovers secrets that test his courage and beliefs.

Friends Petr and Michal, who have known each other since high school, live completely different lives: one has already settled down, has a well-paid job and a family, the other is a loner with unfulfilled artistic ambitions. But they are still united by their passion: graffiti.
