The victim becomes the aggressor in “”Wait Until Dark,”” a thrilling crime drama directed by Dave Sewell at the Beowulf Alley Theatre.

Susy Hendrix, performed brilliantly by Dallas Thomas, is a blind woman who becomes entangled in a desperate ploy to steal a doll filled with heroin.

The story starts slow but picks up quickly as the crime takes shape.

The animated Steve McKee plays Mike Talman, an expert con artist who steals Susy’s trust in order to find the doll.

Benjamin Dygert acts as Talman’s bumbling partner-in-crime, and they both answer to the evil head Harry Roat, performed by Gary McGaha.

An unlikely hero, Hendrix foils the meticulous plan when she cuts power to her apartment, plunging the theatre into dizzying darkness.

Thomas’ performance in a challenging role is more than convincing. She easily steals the spotlight from the otherwise average talent on stage with her.

McGaha falls short of creepy as Harry Roat, which takes away from the overall suspense – especially during the final scene. He seems too focused on speaking with a heavy New York accent that distracts from his character.

The stage script, written by Frederick Knott, was adapted to film in 1968, and Audrey Hepburn first played Susy on the big screen. UA graduate Beth Dell manages Beowulf Alley, where “”Wait Until Dark”” plays through Oct. 12.

Beowulf Alley Theatre is located at 11 S. Sixth Avenue.
