'Slowgirl' extended for one week at Steppenwolf

“Slowgirl” has become a hot property. So the Steppenwolf Theatre production of Greg Pierce’s play — a two-hander starring William Petersen and Rae Gray, directed by Randall Arney — has been extended for a week. It will now run through Sept. 1.

Pierce’s play is set in the wake of a tragic event at a house party in Massachusetts. Becky, a 17-year-old girl involved in the incident, takes temporary refuge with her uncle, Sterling, who lives in an isolated retreat in the Costa Rican jungle. As uncle and niece get reacquainted over the course of a week, details about their pasts slowly unfold.

Tickets for the extension ($20-$78) go on sale Aug. 6 at 11 a.m. Call (312) 335-1650 or visit www.steppenwolf.org.
