Jan Karski, a hero of the Polish Underground Resistance who tried to shake the conscience of the world in 1942 when there was still time to act to stop the Holocaust. 

A Roman Catholic, Karski volunteered at great risk to undertake a mission on behalf of the underground government to carry eyewitness reports to the free world about the destruction of the Jewish people of Poland. In this politically-charged play, Karski, who after the publication of his best-selling book Story of a Secret State became a legendary Georgetown University Professor, engages with a chorus of students who urge him to reckon with the ghosts of his past and to "go back" in his memory to revisit the episodes and memories that haunt him in order to bear witness for future generations. The chorus then begins to enact that history, filled with episodes of political intrigue, physical courage, harrowing escapes, tenderness, and devastation.
