Here's the Steppenwolf subscription season at a glance:

Sept. 8-Nov. 6
Clybourne Park
By Bruce Norris
Directed by ensemble member Amy Morton
Featuring ensemble member James Vincent Meredith
In the Steppenwolf Downstairs Theatre
"On two separate afternoons, 50 years apart, a modest bungalow on Chicago's northwest side becomes a contested site in the politics of race. September 1959: Russ and Bev are moving out to the suburbs. They've inadvertently sold the house to the neighborhood's first black family and ignited a community showdown. September 2009: the neighborhood is ripe for gentrification and the house is again changing hands. This time to a young white couple with plans for demolition and a knack for saying the wrong thing at the wrong time. In a provocative nod to A Raisin in the Sun, longtime Steppenwolf collaborator Bruce Norris takes a hilarious look at what happens when home becomes a battleground." Dec. 1, 2011-Feb. 5, 2012
Penelope
By Enda Walsh
Directed by ensemble member Amy Morton
Featuring ensemble member John Mahoney
In the Steppenwolf Downstairs Theatre
"On a sun-scorched island off the coast of Greece, beautiful Penelope awaits the return of her husband from war. Beneath her window, four Speedo-clad men camp in an empty swimming pool, a cock-eyed internment where both provisions and time are running low. Locked in a do-or-die competition to win Penelope's love, they preen and posture and connive in a last ditch effort to cheat a grisly fate. Penelope, the newest play by powerhouse Irish playwright Enda Walsh, is an eloquent, wildly funny riff on life, love and the war at home."

Jan. 19-May 13, 2012
Time Stands Still
By Donald Margulies
Directed by ensemble member Austin Pendleton
Featuring ensemble members Francis Guinan and Sally Murphy
In the Steppenwolf Upstairs Theatre
"For photojournalist Sarah Goodwin, happiness is rushing from hotspot to hotspot capturing images of global conflict. When she barely survives a bomb blast in Iraq, she's forced to return home into the care of her long-time lover, James. She's caught off-guard by James's desire for family and by the simple domestic life pursued by Richard, her editor, and his much younger girlfriend, Mandy. Pressed to consider settling into a 'normal' life, Sarah must confront her addiction to the drama and chaos of war. From Pulitzer Prize winner Donald Margulies, Time Stands Still is a witty, intelligent look at what happens when ordinary life is refracted through the lens of war."

April 5-June 10, 2012
The March
Based on the novel by E. L. Doctorow
Adapted for the stage and directed by ensemble member Frank Galati

In the Steppenwolf Downstairs Theatre
"General William Tecumseh Sherman, Uncle Billy to his men, marches 62,000 Union soldiers through lush Georgia countryside. Bearing along both black and white refugees, the march destroys everything in its path, turning home into exile and exile into home. Its epic force forever changes the lives of those caught up in its sweep: a liberated slave, a sheltered daughter of a Southern judge, a pair of Confederate deserters and Uncle Billy himself. The March is a story of momentous upheaval and the limits of courage and love."

June 28-Aug. 26, 2012
Three Sisters
By Anton Chekhov, adapted by ensemble member Tracy Letts
Directed by ensemble member Anna D. Shapiro
Featuring ensemble members Ian Barford, Ora Jones and Sally Murphy
In the Steppenwolf Downstairs Theatre
"The Prozorov family chafes at the constraints of life in their small provincial town, once a bustling army garrison where their late father served as general. Attempts to shore up their crumbling social status lay bare the larger forces of unrest that will soon engulf them all. Tony Award-winning ensemble members Tracy Letts and Anna D. Shapiro continue their celebrated collaboration, bringing fresh insight to this classic story of a privileged family's changing fortunes."
