Good-natured and garrulous, Schweik becomes the Austrian army's most loyal Czech soldier when he is called up on the outbreak of World War I -- although his bumbling attempts to get to the front serve only to prevent him from reaching it. Playing cards and getting drunk, he uses all his cunning and genial subterfuge to deal with the police, clergy, and officers who chivy him toward battle.

Kaspar Len returns home after three years in the army. He vainly searches for the mason Kryštof’s family where he had lived before he left. All he finds out is that Kryštof’s daughter Márynka, who was in his thoughts all those years, is now working in the local brothel. He goes to visit her and Márynka tells him of the misfortunes which befell her family.
