One is ordered to go to the camp of King Karl XII of the Swedes while the other is sent to the camp of Russian Tsar Peter the First. Both Frenchmen face various dangers along the way. They witness the grand battle of Poltava from opposite sides. Court plots and romantic adventures stay in the past as both are plunged head first in the boiling pot of war and the horrors it brings into their lives.
