“Gone Signal” is formally organized around a question that theater has not often asked this directly: what does it mean to search for someone when the searching itself becomes a performance? Miriam Tanaka-Osei’s new play, which announced its cast this week for a limited run at The Drift’s downstairs space in Hell’s Kitchen, follows seventeen-year-old Adaeze as she recruits strangers through a volunteer experiment platform to reconstruct her brother’s last known online activity — and the structure of the play mirrors, almost exactly, the structure of that experiment.

Claudette Ferris will play Adaeze, with previews beginning September 8. Ferris comes primarily from physical theater — she trained at the Movement Lab at Copeland College — and Tanaka-Osei has written a role that is going to need exactly that. Adaeze does not simply speak; she navigates, she performs her grief for an audience of strangers, she manages the interface. The casting makes sense in a way that suggests someone, either Tanaka-Osei or director Brenna Shoji, has thought carefully about what this role requires technically, not just emotionally.

The formal structure of “Gone Signal” is what makes it interesting as a text, and interesting as a problem. Tanaka-Osei has written the play in what she describes in a production note as “layered simultaneity” — multiple scenes happening in overlapping time, each representing a different thread of Adaeze’s investigation, each interrupting and contaminating the others. It is not unlike what Caryl Churchill was doing in “Top Girls” with her temporal doubling, except that Tanaka-Osei is less interested in history as the disrupting agent and more interested in information architecture: the way that digital search rewires how we understand sequence, causation, evidence.

That is a genuinely structural claim, and the script supports it more than you might expect from a premise that could easily have become an issue play about teenagers and the internet. Tanaka-Osei is a playwright who has read her Churchill, clearly, but she’s also working in the lineage of testimonial form — scenes where Adaeze’s volunteer searchers speak their motivations for participating directly to the audience, framed as experiment logs. These interludes are both formally necessary and dramatically effective in a way the form earns. They do not feel like devices. They feel like the play found the only honest way to include its secondary characters.

The limitation, and it is worth naming, is that the brother — the absent center, the disappeared — remains entirely undeveloped in the material released so far. This is presumably intentional. The production notes frame the brother’s opacity as a structural choice, the point being that Adaeze’s investigation constructs him rather than discovers him. That is a defensible formal position. It is also a difficult one to sustain across ninety minutes, and the history of plays built around a structuring absence suggests the negative space has to be shaped with considerable care. Pinter did it. Kane did it. The risk for Tanaka-Osei is that without a specific, formal absence — shaped, pressured, given contour — the hole at the center reads as underdevelopment rather than architecture. I am waiting to see whether the production earns the choice or simply assumes it.

The rest of the cast — Desmond Park as the experiment platform’s administrator, Yuki Osei as the volunteer most entangled in Adaeze’s search, and a rotating ensemble of four others — suggests a group approach to what is ostensibly a solo investigation, which is another formal bet. You can see why Shoji would make it; the question is whether the staging allows Ferris to hold the center when the play is actively redistributing its attention.

“Gone Signal” runs six weeks at The Drift, with performances through October 19. If Tanaka-Osei’s script does what its structure promises, this is exactly the kind of play that translates formal experiment into emotional necessity. If it doesn’t, it will still be the most interesting failure downtown this fall. Either way, that is a reason to be in the room.
