In the play, David emigrates to America in the wake of the 1903 Kishinev pogrom in which his entire family is killed. He writes a great symphony called "The Crucible" expressing his hope for a world in which all ethnicity has melted away, and falls in love with a beautiful Russian Christian immigrant named Vera. The dramatic peak of the play is the moment when David meets Vera's father, who turns out to be the Russian officer responsible for the annihilation of David's family. Vera's father admits his guilt, the symphony is performed to accolades, David and Vera live happily ever after, or, at least, agree to wed and kiss as the curtain falls.
