Preston will play a single mother struggling to keep her life in order after her husband abandons her, forcing her to raise their two daughters on her own. Trachtenberg will play the older daughter.

The drama will shoot in January in South Carolina.

Brad Wyman, Donald Kushner and Patty Jenkins -- the team behind the Oscar-winning Charlize Theron starrer "Monster" -- are producing. Joel Stevens is an executive producer.
