Scott Elliott will direct Francine Volpe's drama, which will officially open Nov. 15 for a run through Dec. 22. The Good Mother launches the New Group's 2012-13 season.
Mol (Chicago, The Shape of Things, "Boardwalk Empire") will be joined by Darren Goldstein (Bloody Bloody Andrew Jackson), Alfredo Narciso (The Ugly One), Eric Nelsen (13 the Musical) and Bill Sage (Aunt Dan and Lemon).
Here's how it's billed: "In this taut psychological thriller, Larissa (Mol) is a single mother who can barely meet the mortgage on her house in Mount Vernon, NY. When a bizarre incident involving her 4-year-old daughter forces her to face someone from her past, her own questionable actions come back to haunt her."
Volpe's plays include The Given, Late Fragment, Sweethearts and Giftbox.
The Acorn Theatre is located at 410 West 42nd Street. For tickets, phone (212) 244-3380 ext. 305, or visit TheNewGroup.
