 A painter in the Theresienstadt Ghetto draws sketches of Nazi atrocities, inorder to expose the German hoax about the  Model Jewish Ghetto.  Her daughter, Irena, smuggles the drawings out of the Ghetto and to the Czech partisans. As the Nazis get hold of the drawings, Irena does not admit that she is the smuggler, and three innocent friends are executed in her place.
