What if a fascinating stranger knew you better than you know yourself?

When her husband comes home with a farfetched story about eating dinner with someone he believes to be Jesus, Mattie Cominsky thinks this may signal the end of her shaky marriage. Convinced that Nick is, at best, turning into a religious nut, the self-described agnostic hopes that a quick business trip will give her time to think things through.

On board the plane, Mattie strikes up a conversation with a fellow passenger. When she discovers their shared scorn for religion, she confides her frustration over her husbands recent conversion. The stranger suggests that perhaps her husband isnt seeking religion but true spiritual connection, an idea that prompts her to reflect on her own search for fulfillment.

As their conversation turns to issues of spiritual longing and deeper questions about the nature of God, Mattie finds herself increasingly drawn to this insightful stranger. But when the discussion unexpectedly turns personal, touching on things shes never told anyone, Mattie is startled and disturbed. Who is this man who seems to peer straight into her soul?
