Loy Arcenas stages the work by the downtown company's co-founder slated to open Dec. 5 for a run through Dec. 16.

The post-World War II, Vietnam-set drama takes place in a world "when Ho Chi Minh had visions of a free country and a newly formed House UnAmerican Affairs Committee blacklisted a young, female American writer who believed in truth, justice and a humane social order," according to an announcement.

The cast features Jayne Haynes (The Serpent, Terminal) as Herbst, Arthur Acuña (The Romance of Magno Rubio, Trial By Water) as Ho as well as Christian Baskous, Drew Hildebrand (Screen Play) and Claro Austria.

The design team includes Ben Stanton (lighting), Oana Botez-Ban (costumes), Leah Gelpe (sound). Arcenas provides his own set.

Playwright Wellman penned the recent plays Bitter Bierce (PS 122) and Jennie Richee (Ridge Theater). The 2003 Lifetime Achievement Obie Award winner is currently at work on an opera (with composer David Lang) called The Difficulty of Crossing a Field. Next up, The Flea teams with The Chelsea Art Museum on the holiday-themed event Twas The Night Before... (Dec. 13-23) featuring ten-minute plays by Wellman, Christopher Durang, Len Jenkin, Roger Rosenblatt and Elizabeth Swados and starring The Bats. The new year will welcome Golden Motors and The Rose Project — two musicals worked on as part of a five-week residency by Music Theatre Group. The New York premiere of Charles Mee's Limonade Tous Les Jours as directed by Flea artistic director Jim Simpson will close out the season (March 8-April 28, 2007).

Tickets to Two September at The Flea Theater, 41 White Street (between Broadway & Church Streets) are available by calling (212) 352-3101 or online at www.theflea.org.
