In the fog-laden hills of 19th century Ireland, secrets whisper on the wind, and the line between salvation and damnation blurs with each passing hour.

Colleen O'Byrnes, a woman bound by duty and driven by desperation, embarks on a harrowing journey under the shadow of Samhain's eve. With a shovel in hand and the weight of her family's legacy heavy on her shoulders, she dares to disturb the sanctity of the dead to reclaim what was stolen.

But in the darkness of that fateful night, truths unravel and betrayals surface, plunging Colleen into a maelstrom of deceit and violence. Accused of crimes she did not commit, she finds herself shackled by the chains of injustice, with only one ally: Reardon McGiffin, a man whose loyalty knows no bounds.

Fleeing to the distant shores of America, Colleen seeks solace in anonymity, yet fate has other plans. Ten years of penance at The Sisters of the Eternal Flame Sanatorium cannot erase the past's sins, and when shadows from yesteryears come knocking, Colleen is forced to confront the ghosts she thought she buried long ago.
