This romantic story turns on a stirring infatuation that takes hold of three young people under the influence of Simon, a Prague student. After the study year, 18 year-old Julio returns to his parental home, a little chateau on the Otava river. There he converges with his childhood friend Petr and the young boatman's daughter Klárka. Sharing her beguilement with Simon, who has quickly turned a tranquil summer atmosphere into a relationship drama, is Julio's cousin Rosa.—NFA
