In London, the summer marks a milestone of a different kind for Edie: a decade married to the love of her life, and their first child on the way.

Fearing the worst, Edie scours the city for her missing husband, and eventually she unearths a clue: Joe's wedding ring, alongside a note urging her towards Paris. Using her heart as a compass, Edie sets off on a journey that takes her across Europe, following a trail that promises to unlock the mystery and lead her to Joe.
