Based on a Story explores the widely-publicized encounter between a Jewish Cantor, Michael Weisser, and Nebraska's former Ku Klux Klan Grand Dragon, Larry Trapp. After months of harassment from Trapp by mail, phone and cable TV, the Weisser family befriended Trapp, who then renounced the Klan, moved into the Weisser family's home and converted to Judaism. Trapp, who was a double amputee and blind from childhood diabetes, died in the Weisser's home six months after he moved in.
