Jane and Lily are the best of friends, old college roommates, and they believe they tell each other everything. From Lily's perfect marriage to Jane's on-again, off-again romances, the two women trust each other with all their secrets.

When Lily winds up in a coma in the hospital, all evidence points to her husband. Except for the pictures littered around the crime scene, pictures of a naked woman with her face blurred out and Jane's name scratched on the back of the photos.

Jane starts her own investigation to find the truth—after all, Lily would have told her if she was having marital problems—but when she discovers Lily's secret life, she starts to believe that not only is Lily not innocent, but she's not who Jane believes her to be.

In a tangled web of mystery and secrets, two friends must learn that no one is who they seem, and discover their own truths buried in their lies.
