Consider this plot: The Chicago Cubs finally are going to win the National League pennant. But that will cause the world to come to an end.

To many Cub fans, the idea isn't so far fetched - it's been 45 years since their heroes last played in a World Series.So "The Last Pennant Before Armageddon" - a play about a potential Cub victory that would start World War III - was a natural for the City Lit Theater, only three blocks from the baseball club's Wrigley Field.

The comedy is based on a short story by W.P. Kinsella, whose "Shoeless Joe" was made into the successful film "Field of Dreams."

The play revolves around a seventh playoff game between the Cubs and Los Angeles Dodgers, flashbacks of fictional Cub manager Al Tiller's loser past, and God's deliberations before a court that includes Al Capone, the late Mayor Richard J. Daley and the Marx Brothers.

Tiller, played by actor Dan Payne, dreams that the team's losing tradition is God's fail-safe mechanism for preventing the world's end.

"I don't know what I want to do now - throw the game, lose the pennant, save the world?" pines Tiller.

The production replicates the feel of the ballpark. An organist pumps up the crowd, vendors hawk candy and the audience is asked to stand for the "Star-Spangled Banner" and "Take Me Out to the Ballgame."
