Margaret (Sundance stalwart Rebecca Hall) has her life in careful order. Her sleek apartment, high-powered job, chic power suits, reliable fuck buddy – it’s all precisely crafted and, most importantly, controlled.
In the opening scene, she’s doling out advice on how to deal with a toxic boyfriend to an intern impressed by her wisdom and composure. She heads home to take care of her teenage daughter. But there are slight cracks. Her married paramour is a little too interested, her daughter a little too smothered. So when a sinister figure from her past crash-lands into her life, those cracks start to deepen and Margaret starts to unravel.
