A Chicago premiere of a New York drama written by an American playwright who lives in London. Those are the ingredients of Disappeared , a Phyllis Nagy drama which will be presented by two Chicago companies -- the famous Steppenwolf Theatre Company and the rising Roadworks Productions -- at Steppenwolf's Studio Theatre Feb. 3-28 (opening Feb. 6). Disappeared concerns Sarah Casey, a young travel agent who suddenly vanishes from a dingy Manhattan bar. Hell's Kitchen, O'Malley's Saloon and the NYPD are examined in the story, as is Elston Rupp, a thrift store clerk who may have kidnapped Casey, or, perhaps, escaped along with her.

Though U.S. born, Nagy found her fame overseas. Her most recent play, Neverland , opened at the Royal Court Theatre.

The Roadworks staging will star Debbie Bisno, Stephanie Childers, Marilyn Dodds Frank, Derek Hasenstab, Danny McCarthy, Larry Neumann Jr., Si Osborne and Nathan Rankin. Abagail Deser will direct. Previous Roadworks productions include the Chicago premieres of SubUrbia , Ecstasy and Dealer's Choice.
