With all the news over the past decade about priests sexually abusing young boys, the climactic admission in Ronan Noone’s play is unsurprising. And as we’re waiting for the situation’s full ugliness to be revealed, an uneven cast dulls the drama of discovering the long-term consequences of a priest’s offenses against a classroom of Irish schoolchildren. And yet Michael S. Pieper’s production can be entertaining and affecting. Anthony Cummins and Ehren Fournier are particularly credible as two of the classmates, one a righteous victim seeking justice, or at least acknowledgment, and the other a more broken-down man who wants the past left buried. It’s regrettable that the other actors overplay for laughs or get overwhelmed by the emotion the script demands, because when the cast is confident, this meaty material makes for a good show. Through 12/4: Thu-Sat 8 PM. Boxer Rebellion Theater, 1257 W. Loyola, 773-465-7325. $10-$15.
