At 57, Julia Ames has found herself with an improbably lovely life. Despite her inclination towards self-sabotage, she has a husband she loves, two happy children and a quiet, contented existence in the suburbs. But, out of the blue, things begin to change. Her always well-behaved son, Ben, is acting strangely, and will soon make a shocking announcement. Her beloved but belligerent teenage daughter is about to depart for college, leaving Julia unexpectedly terrified of an empty nest. And, in the local grocery store, Julia encounters a woman she hasn’t seen for 20 years – a woman whose friendship was once both her lifeline and, very nearly, her downfall. Consumed with her checkered past and the chaos of her present, Julia starts to spin out of control, at risk of destroying all she most loves.
