Diane (Mary Kay Place) puts the needs of everyone around her first. She spends hours at the side of her terminally ill cousin Donna (Deirdre O'Connell) in the hospital, she volunteers at her local soup kitchen, she drops in on elderly friends and tries to save her troubled, drug-addicted adult son Brian (Jake Lacy) from himself, bringing groceries and clean laundry to his apartment.

But beneath her relentless routine of self-sacrifice, Diane is fighting a desperate internal battle, haunted by a past she can't forget and which threatens to tear her increasingly chaotic world apart.
