Back in 1999, a group of high school students in Kansas discovered a reference to a little-known Polish woman who supposedly rescued 2,500 Jews from the Nazi regime during World War II. Stunned by their discovery, they dug for more information and wrote a short play about the woman, and figured that would be the end of it. Instead, the play has seen more than 200 performances worldwide, and the rescuer, freed from obscurity, has been nominated for a Nobel Peace Prize.
