A pianist named Garvey, while traveling on a tour, gets off the train to buy cigarettes, and learns from a salesgirl that the cities imagined by Grin really exist. Forgetting about his tour, he goes to one of these cities, where he meets the captain of “The Waverunner”…

Three young men, who have become friends while doing their national service, make their way in the world.

The beginning of the 18th century. Bulgaria is under the Ottoman bondage. The monks of the Monastery of Hilendar on Mount Athos warn the young monk Paisiy to beware of the "pestilent chapel". On his deathbed, the abbot conjures Paisiy to search for Slavonic books. The young monk goes from one monastery to another in search of ancient books. He breaks into the "pestilent chapel" and finds there stacks of old Bulgarian books telling of the wisdom of Bulgarians kings, and of the power and civilization of the Bulgarian Empire and its past glory. His fellow-monks try to burn the books but Paisiy manages to escape. His Slav-Bulgarian History circulates in handwritten copies through the captive country and the Bulgarians becomes truly aware of their national identity.

The action takes place at the end of WWII. It is 1944 on the Yugoslav front, where the Bulgarian Army is fighting bloody battles against the retreating Nazi units. Several lorries loaded with Bulgarian soldiers make a detour so as to deliver ammunitions to an army unit. They are people with different convictions sharing a common goal - to come out victorious and to return to their peaceful everyday life. Among them are people who believe in the triumph of the new system and for whom the difficult crusade is a confirmation of their ideals. They are also uncertain people. For the youngest this is the first trial in life. A young Yugoslav woman helps them find the road through the dangerous front line. Her romance with the one of Bulgarian soldiers symbolizes solidarity in the struggle against the common enemy. After a series of difficulties and mishaps, the soldiers manage to deliver the ammunitions to their comrades.
