In the small, affluent town of Fairview, Connecticut, everything seems picture perfect. Until one night when young Jenny Kramer is attacked at a local party. In the hours immediately after, she is given a controversial drug to medically erase her memory of the violent assault. But in the weeks and months that follow, as she heals from her physical wounds, and with no factual recall of the attack, Jenny struggles with her raging emotional memory. As they seek help for their daughter, the fault lines within Tom and Charlotte's marriage and their close-knit community emerge from the shadows where they have been hidden for years.
