 Celebrates Sister Rose Thering, for 67 years a Dominican nun. Her passion is anti-Semitism. Archival footage looks at her growing up in Wisconsin and taking the veil in her teens. Interviews with scholars and common people capture the extent to which "Christ killers" was a standard Catholic description of Jews. Sister Rose s research at Saint Louis University in the 1950s into the presentation of Jews within Catholic educational materials leads to the publication of "Nostra Aetate," a document released in 1965 by the Second Vatican Council. Since that time, she s dedicated herself to eradicating anti-Semitism. The film ends with a critique of Mel Gibson s "Passion of the Christ."
