In the last episode, Arnout travels through Ukraine in an old jeep. Where the First World War once raged, he relives the most exciting days in the lives of Oscar and Marcel Thiry. In 1916, the brothers are part of the first armored corps of the Belgian army. King Albert I lends the armored corps to his ally, Tsar Nicholas II of Russia. The Belgians fight together with Russian soldiers against the troops of Austria-Hungary and Germany. But the resistance is great and Oscar is wounded and taken to the city of Ternopil. In the tumult of war, both brothers become separated from each other. The clock is ticking for Marcel Thiry: he must find his brother before the advancing Austrian army takes over the entire city.
