Journalist and suburban mom Claire Cooper suffers from panic disorder. Most of her anxieties seem irrational, nothing that can't be fixed with the help of some Xanax. But late one stormy summer night, when her husband, Sam, is away on one of his frequent business trips, Claire's fears come to life. She discovers an intruder has broken into her young daughter's bedroom. She watches helplessly as he picks up her sleeping child from her bed. Desperate to protect her family, Claire puts herself in the line of fire and utters the plea that will undo her: "Take me instead." As she drives away in the kidnapper's car, Claire fears for her children, but not for herself. And she can't help noticing the reversal in her marriage -- for the first time in ten years, Sam will not know where she is.
