The production, which launches the sixth season of Roundabout Underground, will officially open Oct. 30 and continue through Dec. 30. All tickets for Roundabout Underground stagings are priced $20.

Directed by Daniel Aukin, the cast features Tracee Chimo (Daphna), Philip Ettinger (Jonah), Molly Ranson (Melody) and Michael Zegen (Liam).

Bad Jews, according to the Roundabout, is a world-premiere comedy about the "holy and the holier-than-thou. Daphna Feygenbaum (Chimo) is a Real Jew — just ask the Israeli boyfriend she met on Birthright. So when her cousin Liam (Zegen) brings home his shiksa girlfriend Melody (Ranson) and declares ownership of their grandfather's Chai necklace, it sparks a viciously hilarious brawl over family, faith and legacy."

The creative team includes Lauren Helpern (sets), Mark Barton (lights) and Dane Laffrey (costumes).

Show times are Tuesday through Sunday at 7 PM with matinees Saturday and Sunday at 1:30 PM.

Tickets are available by calling Roundabout Ticket Services at (212) 719-1300, online at roundaboutunderground.org or at the Harold and Miriam Steinberg Center for Theatre box office (111 West 46th Street). All tickets are issued as general admission passes for first-come, first-served seating on the show date.

Roundabout Underground is an initiative "to showcase new plays that will either allow an experienced director to go back to his/her creative roots or give a debut production to an emerging writer or director. Robyn Goodman (artistic producer to the Roundabout), who has significant artistic development experience, curates the initiative that continues to be a creative breeding ground for nurturing new talent."
