The film is about soviet falsification of historical
events of reuniting Ukraine with Russia. In 1954 in
the Soviet Union the textbooks on history were hastily
rewritten changing the term "joining" by
"reuniting". The Ukrainian historians who
raised objections to the state policy were discharged.
The film is made on the bases of documents of the
Pereyaslavska Rada (Pereyaslav Council) and Bohdan
Khmelnytskyi' "March clauses".
