“Faceless” may well leave you breathless.

Selina Fillinger’s timely new play about identity and faith expresses its myriad ideas so quickly and so unrelentingly that it threatens to overwhelm the audience.

“Faceless”

Fillinger gives us plenty to ponder in this sharply written, 90-minute courtroom drama about an American teenager and convert to Islam who’s recruited by terrorists into aiding their cause.

Developed through Northlight Theatre’s Interplay Program, the company’s blistering world premiere is helmed by Northlight artistic director BJ Jones. And his taut production boasts an A-list cast.

Susie Glenn (an impressive Lindsay Stock) is a bright 18-year-old high school senior somewhat adrift in the wake of her mother’s recent death. Grief-stricken, she gets little solace from her emotionally distant father, Alan (Joe Dempsey), whose profound sorrow prevents him from properly comforting his daughter.

Isolated and vulnerable, Susie — a social media devotee — is a prime candidate for online recruitment and radicalization by extremist groups. Through a series of flashbacks, we watch a lonely teen get seduced by a shadowy, online acquaintance who claims to be a jihadist. Within months, Susie has converted to Islam, become engaged to the mysterious Reza (her online recruiter) and arranged to travel to the Middle East to join ISIS.

Federal authorities get wind of her plans and charge her with supporting terrorists. Her defense attorney, Ross Lehman’s avuncular Mark Arenberg, believes she has been manipulated and misled. He urges her to accept an insanity defense as a way of mitigating the significant prison sentence that would likely follow a conviction.

But a lengthy prison sentence is exactly what Scott Bader — an assistant U.S. attorney with political aspirations — seeks.

Bader (a crisp, calculating Timothy Edward Kane) wants to send Susie to federal prison for 20 years. To accomplish that, he enlists fellow federal prosecutor Claire Fathi (Susaan Jamshidi), a Harvard University-educated Muslim woman of Iranian descent. Bristling at what she perceives as tokenism, Claire initially rejects Bader’s offer of second chair.

“I don’t use my faith to fight my battles. That’s what ISIS does,” she tells him.

Bader replies that he will use every means available to fight this, insisting “that’s what America does.”

Fillinger, a promising young playwright and a recent Northwestern University graduate, is a good writer with a lot to say. To that end, she draws striking parallels between the female characters, including their choice to wear the hijab and the patronizing way they’re treated by men in superior positions.

Susie’s attorney calls her “kiddo.” Bader asserts his authority over Claire more overtly, making clear who is in charge and going so far as to feed her answers during a news conference.

Jones’ incisive staging further reflects the gender imbalance. Several times, the men address the women from a standing position while the women remain seated. This is especially true during the scenes depicting Susie’s communication with the jihadist Reza. He looms behind her — reflecting the dual threats of terrorism and paternalism.

Parenting figures prominently in “Faceless,” which suggests its absence leads to a person becoming disconnected and isolated, which in turn allows extremist beliefs to take root. It’s an intriguing theme, one of several Fillinger explores. That said, “Faceless” tends to embrace cliches and the play looses its footing a bit near the end.

But Jones’ cast — which includes several Chicago-area veterans and newcomer Stock — impresses. Stock in particular delivers a deeply felt performance that combines vulnerability and delicate naivet
