“Sweat,” the Pulitzer-winning drama making its Indy premiere at the Phoenix Theatre, is a riveting mystery wrapped in a stark examination of recent events.

Set in a Pennsylvania Rust-Belt town, we first meet Jason (Nathan Robbins) and Chris (Ramon Hutchens) as they talk to their probation officer (Josiah McCruiston). The former best friends are released from prison in 2008, having served time for what they did eight years earlier. Neither has come to terms with their act; Jason literally wears the shame on his face.

Much of the rest of the play takes place in the year 2000, in a bar near a local factory where generations of men and women have worked good Union jobs. But the changing times, aided by economic factors such as NAFTA and the decline of labor unions, have cast an air of uncertainty over the town. One plant, where Chris’s father Brucie (Dwuan Watson) worked, shut out its workers and may never reopen. But his mother, Cynthia (Dena Toler), is doing fine at her workplace, where she and her friends Jessie (Angela Plank) and Jason’s mom, Tracey (Diane Kondrat), even consider going for a recently-opened management position.

Bartender Stan (Rob Johansen) used to work at the factory, but thanks to an on-the-job injury he settles for just selling his old friends drinks. He is helped by good-hearted Oscar (Ian Cruz), who patiently puts up with the patrons assuming he’s Mexican (his family’s Columbian) and that he’s an immigrant (he was born in the town, like everyone else).

As for individual performances, director Bryan Fonseca has once again brought out the best in a very solid ensemble, familiar to Phoenix audiences.

As we see the social and economic darkness descend upon these characters, and we get to know their feelings and fears as we watch the inevitable from our perspective of over a decade later, one haunting truth lingers in the background: Something very bad is going to happen to one of them. We never really know until the moment it happens, and at that point, we truly feel the dark side of 21st-century America.
