The year 1918 is the milestone of modern-day Czech independence, and it is at the beginning of this yearthat a work of Czech provenance, Jenůfa, appeared on a world-renowned Viennese stage.

The story of Jenůfa’s falling in love concerns the substance of relationships and love, both between partners and between mother and child.
