The film focuses
on the ongoing investigation which aim is to determine the true birthplace of
the Piast dynasty. Is it, as commonly believed, Gniezno or perhaps the no longer
existing Kalisz-Zawodzie castle? Archaeologists, dendrologists and historians
discuss their for and against arguments for both hypotheses. Thanks to the
computer animations, the viewers can go back to the times of Mieszko I to find
out more about ins and outs of the daily life of castle’s inhabitants and also
to learn about the consequences of the main political events of that time, both
for the contemporaneous descendants and people living in those times. The
film-maker, by the use of an attractive form of narration, combines the
findings of scientific research with the presentation of actual events and
places relevant to the early Polish statehood. If the hypothesis that has been
put forward in the film, is confirmed by the ongoing genetic research, it may
turn out that Kalisz is the cradle of the Piast dynasty.
