The day of reckoning has come to the Fitzgerald Theater in St. Paul, home of A Prairie Home Companion. The show is closing, the theater is going dark. Radio station WLT has been sold to a broadcasting conglomerate in Texas. The wrecking ball is poised to swing as the regulars arrive for the last broadcast in a state of disbelief - the Johnson Girls, Yolanda and Rhonda, and the singing cowboys, Dusty and Lefty, crooner Church Akers, and announcer Garrison Keillor. But when the Dangerous Woman appears with her golden Botticellian hair and dazzling white trench coat, the final curtain catches them all by surprise.
