Set in Port Elizabeth during the advent of apartheid, Athol Fugard's 1982 drama depicts a horrible coming-of-age: a teenage Afrikaner turns on two black servants, better fathers to him than his drunken dad, and insists they call him Master Harold instead of Hally. A parable without preaching, the script exposes the fears and frailties that spawn racism and reveals the bigot's isolation, cut off from his best nature--and here from his best friends. K. Todd Freeman's nearly perfect 80-minute staging draws on the cast's strengths: Cedric Young is wise and worthy Sam, Kenn E. Head is the less patient Willie, and Nick Ferrin is the anguished boy who grows up fast and wrong one rainy afternoon in 1950. Through 10/30: Sat-Sun 11 AM. Steppenwolf Theatre Company, downstairs theater, 1650 N. Halsted, 312-335-1650. $12.
