In Dublin, Ireland's capital city, Sophie Ross, a newly married university student, has a bright future before her until the day when the unthinkable happens. Returning home one night, her husband, Adam, walks in on a burglar who stabs him and flees. Adam chases after him but collapses outside the front door and dies in the ambulance on the way to the hospital. In a matter of minutes, the course of Sophie's life changes irrevocably. Raised in a peripatetic family who moved frequently across Europe and North America, her relatives are few and far away, and the aftermath of Adam's murder opens a Pandora's box of painful family and personal history that Sophie must navigate in order to survive.
