The frayed lives of an American man, and a young woman from Ukraine, both painfully impacted by the 9/11 attacks, converge in 2002, and do so again, fifteen years later, with the discovery of their personal journals.

The inexplicable abandonment of these private stories poses a mystery to the finder, Ionia, a Canadian vacationing in Greece, who is hoping to overcome a deeply emotional loss of her own. A journal keeper herself, Ionia is hesitant to invade the privacy of Russell and Mishenka, but is unable to resist upon realizing a man often referenced in their entries is the man she just met.

As Ionia delves into words written years earlier, they touch her in an eerily poignant way, echoing old wounds. It prompts her to behave erratically as she integrates these strangers' stories into her own life, both past and present.
